http://i.imgur.com/hnBwuIj.png An image of the spectrum and the molecular structure.
I'm an undergrad and I have my exam structural analysis in a few days. I was pretty befuddled when I came across this spectrum, since the (usually) broad peak of an alcohol group was missing.
My speculation is that the two phenyl groups cause some steric hindrance, which limits the formation of H-bridges. Can anyone confirm?

SUMMARY: The Drug Enforcement Administration proposes placing the substance amineptine (chemical name: 7-[(10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-yl)amino]heptanoic acid), including its salts, isomers, and salts of isomers, in schedule I of the Controlled Substances Act. This action is being taken to enable the United States to meet its obligations under the 1971 United Nations Convention on Psychotropic Substances. If finalized, this action would impose the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule I controlled substances on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis with, or possess), or propose to handle, amineptine.
DATES: Comments must be submitted electronically or postmarked, on or before September 20, 2021.
How this effects Tianeptine: Under the federal analog act in the USA, if Amineptine is made Schedule 1 in the USA, any Tianeptine sold for human consumption may be treated as it's Schedule 1 related even if not specifically listed under the CSA. There are also laws that allow DHS to seize any structurally related drug of a scheduled substance on import to the USA without specific paperwork.
I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.
Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.
Do your worst!
I'm surprised it hasn't decade.
For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.
I said "hey look, an escaPEA"
No one near me but it didn't half make me laugh for a good hour or so!
Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies π
It really does, I swear!
Theyβre on standbi
Hello, I would just like to have my answer confirmed to be right. Thanks in advance.
Out of all these compounds, which one would have water as their best solvent for recrystalization?
Acetysalicylic Acid Benzil Benzonic Acid Salicylic Acid
My answer was Acetylsalicylic Acid.
Pilot on me!!
Nothing, he was gladiator.
Dad jokes are supposed to be jokes you can tell a kid and they will understand it and find it funny.
This sub is mostly just NSFW puns now.
If it needs a NSFW tag it's not a dad joke. There should just be a NSFW puns subreddit for that.
Edit* I'm not replying any longer and turning off notifications but to all those that say "no one cares", there sure are a lot of you arguing about it. Maybe I'm wrong but you people don't need to be rude about it. If you really don't care, don't comment.
When I got home, they were still there.

This morning, my 4 year old daughter.
Daughter: I'm hungry
Me: nerves building, smile widening
Me: Hi hungry, I'm dad.
She had no idea what was going on but I finally did it.
Thank you all for listening.
You take away their little brooms
