I was preparing spectra for the NMR appendix of my thesis earlier today. I came across a molecule whose 1H spectrum had a peak at 1.56 ppm that I couldn’t explain for quite some time.

Goes to show how long I wasn’t in the lab …

orthocresol

Hahaha

That's an irritating peak.

Jan

Almost as irritating as 0.07 ppm, which always sneaked in =C

You got me damn curious about the lowest voted post. I wonder if I can use my 25 krep tool access to find it o.o

Hi, everyone :-) I've a very very quick question. Is this possible in water:

user228700

$[Pt{(NH_3)}_2Cl_4] (NH_3)→ {[Pt{(NH_3)_2}Cl_4]}^{-2} + {{(NH_3)}_2}^{+2}$

orthocresol

There, that looks better.

And the existence of a salt with $\ce{NH2-}$ anions is questionable.

user228700

Sorry, that was an (NH_3) counter-ion, not NH_2.

user228700

Dyou think that is s'thing that would happen in water?

orthocresol

03:17

If NH3 is a ligand it should go inside the square brackets, so I don't really know what your compound means.

Specifically the red bit: $\ce{[Pt(NH3)2Cl4]}\color{red}{\ce{(NH3)}}$

That's confusing me.

user228700

Sorry! :-/ I mean counter-ion.

orthocresol

But NH3 isn't charged.

user228700

Yeah :-/

orthocresol

So, your product side doesn't really make sense to me either.

user228700

Okay, I'm sorry, that was dumb.

Lingam

The Lingam (IAST: liṅgaṃ, also linga, ling, Shiva linga, Shiv ling, meaning sign, symbol or phallus) is an abstract or aniconic representation of the Hindu deity, Shiva, used for worship in temples, smaller shrines, or as self-manifested natural objects. In traditional Indian society, the linga is seen as a symbol of the energy and potential of Shiva himself. The lingam is often represented alongside the yoni (Sanskrit word, literally "origin" or "source" or "womb"), a symbol of the goddess or of Shakti, female creative energy. The union of linga and yoni represents the "indivisible two-in-oneness...
