@Poutnik ehhhh

k

How was the flight? I wish you happy smile and success.

I have decided yesterday to remove write access of Wizard and Ethan, as their joint participation on straying away topics causes huge traffic. Chemical topics then get quickly out of the sight and get lost in the abyss of the past.

I still keep them in the explicit Read access list(that has no effect, it is used just at private mod rooms to grant ordinary users R/O access), so I can add them back quickly if I change my mind.

@CuckooBeats Me, some years ago, travelling by train on some outdoorsy trip. (I am always in lack of my usable photos, as I do not like taking photos of myself.)

See, still dark, brown hair, cut quite short here as more practical in summer heat under the cyclist helmet.

For very detailed list of 1H-NMR shifts, check the bottom of this chatGPT response

NMR Spectroscopy - organicchemistrydata.org

the second link seems highly useful.

@Poutnik yeah, you have been utterly bullied

@Poutnik sameeeee

@Poutnik :P

@Poutnik XD

@Poutnik hmmmmmm i wonder if you would ever change mind

@CuckooBeats I understand you are travelling on outdoorsy trips by train too - right?

@Poutnik by flight mostly

but also by train

@Poutnik (but you said you had body mass? i dont see any :P)

@CuckooBeats I change my mind often, depending on topic. If it is question of moral integrity, far less often.

@Poutnik i knew it hehe

@CuckooBeats Not yet there, and not so visible at that angle.

and if incase you need data for benzene substitutions LOL

i love this chart already, would take me ages to remember it

It looks like a very ugly NMR case to solve.. :-)

BTW check out this- chemistry.stackexchange.com/questions/187613/…

@Poutnik ummmmm i always encounter benzene derivatives for HNMR now and then

but honestly its easier than aliphatic compounds

You know now NMR much better than I do - I cannot teach you anything in this domain.

cuz you could just see the signals for 6-8 ppm shift and then you know its for benzene

@Poutnik i know hnmr but i know only till the book by janice smith mam describes :)

Exactly - sure things are useful.

@Poutnik you literally look like in your 40's i swear

@Poutnik lemme check the correctness

I have about 48 there...

tehehehheheheeee

mehhhh i got a much better and beautiful table for those values

but still have similar hair - the belly, not so much the same.

I bet there is a beutiful table in your room where you can put all printed sheets with values.

but the site is nice.

@Poutnik i have none pasted on the walls, i am thinking to decorate with p and d-block reactions and salt analysis tho

As I say - I will remove NMR from the chat tags... :-)

@Poutnik NO

@Poutnik this was legit funny

@CuckooBeats Nice idea.

@Poutnik yeah becuz inorganic just vaporizes from my head faster than my perfume

What comes in by your left ear and eye, leaves you by the right ear and eye. Two FIFO buffers.

yay

There are psychological tricks to boost long term memory, by refreshing the memorized stuff at prolonging intervals. You can google it for procedural details.

nah i think my mom is best at that

typical indian parents

It tries to modify exponential function of forgetting to linear function with small slope.

I remember just "My mum is best".

@Poutnik hmmmmmmmmm i wonder what the function is

@Poutnik everyone loves their mothers except when they dont........

ahem

(did u check my question out?)

i gotta go study bruv, i think we definitely got a full org chem syllabus test

i

didnt

understand

anything

but oh why is the half-life of the reaction just 86400 secs?

@CuckooBeats Was going to have a look at it today, I have been assume you will be afk for 3 days.

@Poutnik eh potato potato

@CuckooBeats Assuming it is good for you and not bad.

@Poutnik bad obv

@CuckooBeats How do you know I love potatoes?

mehhh pericyclic reactions why do they even exist, i hate it when i cant solve problems

@Poutnik u said it earlier tats why

@CuckooBeats Exxagerated it says, you have full head of fresh memories, but next day you remember just half of them, and it deteriorates slower but steadily until just major ones remain - some molecules of memories trying to find their erasing reagent.

@CuckooBeats I have said many things, like that you are clever and gifted. It does not mean anything. Unless it does.

Tthese H shift lists - and siblings - are huge

From the same site

There are tons of detailed data, IMHO great complement to your textbooks. the navigator summary list is looooong.

@CuckooBeats Carboxylic Esters:

Benzene - substituent effects:

@CuckooBeats n_memories = n_0,memories * exp[ -ln(2) * (days since the event)]

@CuckooBeats Hermann Ebbinghaus' forgetting curve

Forgetting curve with spaced repetions

@CuckooBeats I am vulnerable to sad woman puppy-like eyes...... fortunately, they have much weaker effect online, unless details photo or video is presented. (What I would never request nor expect.)

@CuckooBeats Picture of memory curve data. Percentage reportedly related to time needed to restore memories of learnt info. So 70% means 30% of time is needed, compared to time to learn first time.

The decrease is slower if there were prior refreshes - as seen on the chart.

@Poutnik you got the same disease as mine, looooong exagerrated words

In German, compound words can be exceptionally long. While some, like "Donaudampfschifffahrtsgesellschaftskapitän" (Danube steamship company captain), are notable for their length, they are not commonly used in everyday language. The longest word in regular use is "Rechtsschutzversicherungsgesellschaften" (legal protection insurance companies), consisting of 39 letters.

@Poutnik i shared you the most embarrassing interview ever, what more do you want?

@Poutnik in inglis isnt it some lung disease ?

Who did you embarrass there?

thanks for the tables, will go through after class

@Poutnik myself duh

Rainbow does not embarrass anybody.

@CuckooBeats No idea.

@CuckooBeats And definitely the site - it is awe inducing.

With this intense chem stuff, I am afraid Pet and Eth would be running for the woods. screaming.....

@CuckooBeats Your nehrusciencecenter link in SE profiles says that "Your account has been suspended".

@CuckooBeats The tables are just few chosen from many.

@CuckooBeats That is why they provide you problems so you could try to solve them. :-P
