Chapter 7, Problem 62E

Interpretation Introduction

Interpretation:

The minimum energy that is required to excite a vibration in $\text{HCl}$ is to be calculated. The wavelength of light that is required to excite the vibration in $\text{HCl}$ is to be calculated.

Concept introduction: According to Einstein light energy comes in packets. These packets are called photons. He states that the amount of energy in the form of photons depends upon the frequency of the photon. The expression for the same is,
$E=h\upsilon$

The value of Planck’s constant $\left(h\right)$ is $6.626\times {10}^{-34}\text{J}$ .

To determine: The minimum energy that is required to excite a vibration in $\text{HCl}$ and the wavelength of light that is required to excite this vibration.
