17
Q

How does conjugation effect UV vis

A

More conjugation = longer wavelengths

18
Q

What is the fingerprint region of the IR spectrum

A

Fingerprint region (1500 - 666) - Unique spectra for different molecules, allows for identification of models

19
Q

How does the IR spectrum work

A

IR absorption corresponds to the vibrational energy levels of the molecule.
