actually, even when magnetically equivalent, protons still couple. it's just that this cannot be observed by NMR because the spin transitions don't have their energies altered by the J coupling.
The cards cover physical, analytical, and organic chemistry. The pricing accommodates monogamous and promiscuous customers by giving the cost per card and noting there is a 20% discount on orders of 8 or more cards.
looks like Blogger doesn't work with anonymous comments from Chrome browsers at the moment - works in Microsoft Edge, or from Chrome with a Blogger account - sorry! CJ 3/21/20
I shudder to think how my wife would react to such a card.

Deleteso they only couple "in private".
The coupling one made me laugh last year, but the person I would give it to wouldn't quite know what to make of it. Such is love.

ReplyDelete... though if any vicinal protons enter the picture, we're splitting.
ReplyDeleteA Hallmark-worthy sentiment!
ReplyDeleteFun fact: One of my aunts is named Allene (the name is related to Aileen). She tells me she hears a lot of chemistry jokes about her name.
