Question

this is a question for my physical chemistry class,

i’m not sure how to go about this. Thank you!

1 . Consider a diatomic molecule irradiated by microwave and infrared light . For parts*
A – C Fill in the quantum numbers for the final state (‘s ) after absorption of the indicated*
photon .
Note : quot; is the election quantum number and is equal to E ( ground state ) are
( excited state ) , quot; is the vibrational quantum number and*I is the rotational quantum
number .
A. Pure rotational
| | |1 – 0. 1 = 4
+
microwave photon*
B. Vibrational – Rotational ( R Branch )
+
infrared photon
[ = $, 11 -0. 1 – 3
+
infrared photon*
C . Vibrational – Rotational ( P Branch )
+
infrared photon*
+
infrared photon
