Solutions

Chapter 6, Problem 73IL

(a)

Interpretation Introduction

Interpretation: The wavelength of the light at the point 2000cm1 has to be determined

Concept introduction:

  • The frequency of the light is inversely proportional to its wavelength.

  ν=cλwhere, c=speedoflightν=frequencyλ=wavelength

  • Wavelength and wavenumber are inversely proportional to each other.

  Wavelength=1wavenumber

  • Planck’s equation,

  E=where, E=energyh=Planck'sconstantν=frequency

The energy increases as the wavelength of the light decrease. Also the energy increases as the frequency of the light increases.

Explanation

(b)

Interpretation Introduction

Interpretation: The high energy and low energy end of spectrum has to be determined.

Concept introduction:

  • Wavelength and wavenumber are inversely proportional to each other.

  Wavelength=1wavenumber

  • Planck’s equation,

  E==hcλwhere, E=energyh=Planck'sconstantν=frequency

The energy increases as the wavelength of the light decrease. Also the energy increases as the frequency of the light increases.

(c)

Interpretation Introduction

Interpretation: The interaction that requires more energy has to be determined among OH or CH.

Concept introduction:

  • The frequency of the light is inversely proportional to its wavelength.

  ν=cλwhere, c=speedoflightν=frequencyλ=wavelength

  • Wavelength and wavenumber are inversely proportional to each other.

  Wavelength=1wavenumber

  • Planck’s equation,

  E=where, E=energyh=Planck'sconstantν=frequency

The energy increases as the wavelength of the light decrease. Also the energy increases as the frequency of the light increases.
