@Buttonwood Hi, apologies for the super-ping chat intrusion. I have noticed you have edited an answer in the resources question. Unfortunately something must have gone wrong. The links you have intended to include are missing. See here: chemistry.stackexchange.com/posts/37310/revisions

@Martin-マーチン No problem, I do not perceive your ping intrusive.

Initially, accessing the page in question in the sort «oldest», the reference to J. Chem. Educ. and the youtube channel was set into the section of «Online courses». Later, yet still at the same hour, I found the entry would suit better the section «Video resources (online)». Thus my thought a cut and paste of the code from one section to the next would afford the intended change.

The sites by khanacademy were not visited by mine for at least a quarter of a year, so I probably cut and pasted lines by accident, too.

@Martin-マーチン Re-reading your ping, however, puzzles me a little. It starts by @@81169 which I speculate intends to use the user number to interact quickly with the users in question.

If so, according to my profile page in ChemSE, my handle would hower be something similar to user:1782 (four decimals only). Maybe a concurrent edit?

@Buttonwood That's the super-ping part, and the number is your chat-id. Moderators can use it to 'summon' a user to chat. I always apologize for these, because some users simply do not want to interact in chat.

Buttonwood

Ok, it is a different counting.

@Buttonwood Well, the markers [4] and [5] were already in use by the post, hence they were substituted where you have used them, too. I have now changed the whole post to use inline notation [text](url) so that it is also easier to maintain. I generally recommend that for the link heavy posts.

Buttonwood

I'm going to retain this for future reference.

@Buttonwood Are the links correct?

Buttonwood

In terms of ANZMAG and JChemEduc, yes in the current form they are correct.

Martin - マーチン

Yes, they work fine.

Buttonwood

@Martin Under your profile, I see that you use GAMESS and Gaussian. Are you aware if there is something like a user group / mailing list for MOPAC, too?

Martin - マーチン

I have not checked all the other links. I noticed some were without https, so that might be worth checking again.

Buttonwood

Or is the simplest to send questions / problems directly to Mr Openmopac?

Re the links: It may be that my web browser's settings allow only https in lieu of http links. Possibly here, too.

Martin - マーチン

I have never used it. I guess it depends on the problem. In any case, there is a new home for such questions right around the corner:

Safdar

@Martin-マーチン how did you type that out?

Martin - マーチン

Hmm... is the above expanding for anyone? Well, here is the backup: mattermodeling.stackexchange.com

@Safdar if you post the url of an se site, it should autoexpand to the logo

Hmmm, it's not working for me

strange...

Buttonwood

From my side, the picture-based representation is seen.

Thanks for the tip for the modeling site. Roger and out.

Q: Why is radiation "contagious"?

So I am reading a book called "Voices from Chernobyl" where witnesses, nuclear plant workers, firefighters and other persons involved in the 1986 accident give testimony of their experiencies. The very first chapter goes along the lines of the wife of a firefigther that was dispatched for duty on...

Q: Yield of possible products from acid catalysed hydration of an alkene with a phenyl group

Here, (b) is the major product due to formation of tertiary conjugated carbocation. My questions are: 1- Will a kinetically favoured (minor) product (c) form? 2- Is product (d) possible due to high temperature? 3- What shall be the order of yield of products?

I'm sorry to ask, but what exactly is the purpose of this chat room? The title leaves a little to be desired haha

Q: What is a Herzberg?

Whatman lists the flow rates for their filters in a unit called a 'Herzberg': What is this? I've been searching around and I did find information about Herzberg flow rate testers, for example this old paper on filtration flow rate measurement and this summary of filtration terminology, but I can...
