I am having trouble distinguishing between primary, secondary and tertiary amines. I read that tertiary amines don't really show a band. I read that N–H wag (primary and secondary amines only) is from 910-665 cm. Im not sure what a "wag " looks like. I am also having trouble matching which amine seen on the spectrum goes to which molecule bc I dont know how to tell what each molecule is (primary , secondary) when its on a benzene ring.
