Question

At what absolute temperatures do molecules occupy each energy level?

Answer 1

At absolute 0 K the molecules occupy energy shells!

Answer 2

$<b<b><font color=red> {ANSWER}$

$<b><font color=orange>$

{ have:Θrot=BekB in units of K, usually in the tens}

{KΘvib=ωekB in units of K, usually in the hundreds or thousands of KΘelec=TekB in units of K, usually in the upper thousands or tens of thousands}

{ K where:Be is the rotational constant in cm−1 for each type of rotational motion }

{(up to 2for linear molecules and 3 for nonlinear molecules).}

{ωe is the fundamental vibrational frequency in cm−1 for each vibration (the number of vibrational motions are 3N−5for linear}

{ polyatomic molecules and 3N−6 for nonlinear polyatomic molecules, where N is the number of atoms). }
