Chapter 11, Problem 11B.3ST

Interpretation Introduction

Interpretation:

Maximum populated level for $OCS$ has to be determined at $298K$ where $\stackrel{\sim }{B}=0.2c{m}^{-1}$.

Concept Introduction:

Maximum populated level of a molecule can be determined using the given formula.

  ${\text{Maximally populated level, J}}_{\max }\text{ = }{\left(\frac{kT}{2hB}\right)}^{\text{1/2}}-\frac{1}{2}$

Wavenumber is the total number of wavelengths observed at a unit distance. Equation for wavenumber can be given as,

  $\begin{array}{c}\text{Wavenumber, }\overline{\text{ν}}\text{ =}\frac{\text{1}}{\text{λ}}\text{ = }\frac{\text{ν}}{\text{c}}\\ \\ \text{where, }\\ \text{λ}\text{=}\text{wavelength}\\ \text{ν}=\text{frequency}\\ \text{c = speed of light}\end{array}$
