Chapter 14, Problem 14.88E

Interpretation Introduction

Interpretation:

The $\text{Si}-\text{H}$ bond distance in silane is to be calculated. Whether the corresponding information can be obtained from the pure rotational spectroscopy or not is to be stated. The reason for the corresponding answer is to be stated.

Concept introduction:

An electronic state of energy has its own vibrational states. The energy between the electronic states is large followed by vibrational states and then rotational states. During an electronic transition, electron from ground state moves straight to the excited state keeping the internuclear distance constant. This is known as the Franck-Condon principle.
