infrared spectra (on this page, and added links to
relevant organic section indexes)
Some simple NMR-IR
problem solving questions
I have included some alternative names and 'old names'
(still in common use - including mine and other internet databases),
BUT, DO NOT USE 'OLD
NAMES' IN EXAMS and ANY OF YOUR ACADEMIC WORK, without good
reason!.
Most of the infrared spectra were produced from thin liquid films, a
few involve the vapour of low boiling compounds and the infrared
spectra of solids can be obtained from a compressed disc of the
organic compound in a two layered potassium bromide KBr disc.
