Chapter 21: Problem 2

The rotational spectra involve (a) a very high energy change (b) small energy changes (c) no energy changes (d) none of these

Short Answer

Expert verified
The correct answer is (b) small energy changes.

Step by step solution

01

Understanding Rotational Spectra

Rotational spectra refer to the part of the molecular spectra that involves rotational transitions. This is typically observed in the microwave region.
02

Analyzing Energy Changes in Rotational Transitions

Spectra stretching over a range of frequencies result due to energy differences in various rotational states. These are not major energy changes, rather, they are typically small.
03

Choosing Correct Answer

From the analysis, it is clear that the correct answer is (b) small energy changes, because the energy differences in rotational transitions are typically small, not very high or nonexistent.
