Question

Discus the fuinciple of electronic spectroscopy
Esplain with refrence to CH2 =CH2, 1,3-butadiende
and carbonyle compounds? ​

Answer 1

Answer:

Electronic Spectroscopy relies on the quantized nature of energy states. Given enough energy, an electron can be excited from its initial ground state or initial excited state (hot band) and briefly exist in a higher energy excited state. ... Without incentive, an electron will not transition to a higher level.

In buta-1,3-diene, CH2=CH-CH=CH2, there are no non-bonding electrons. ... The highest occupied molecular orbital is often referred to as the HOMO - in these cases, it is a π bonding orbital.
