Question

Determine the wavelength for a transition from the v =0 to the v=1 level. Is ts transition in IR region of the electromagnetic spectrum.

Answer 1

no it does not belong to infra red

Answer 2

Answer:No, this transition is not in IR region of the electromagnetic spectrum.

Explanation:

Initial energy level $n_i=0$

Final energy level = $n_f=1$

Wavelength  for this transition is given by: $\lambda$

$\frac{1}{\lambda }=R[\frac{1}{n_{i}^{2}}-\frac{1}{n_{f}^{2}}]$

$\frac{1}{\lambda }=1.097\times 10^7 m^{-1}[\frac{1}{0^2}-\frac{1}{1^2}]=-1.097\times 10^7 m^{-1}$

Since the value of wavelength cannot negative

$\lambda =1.097\times 10^{-7} m$

Range of infrared red rays = $7.5\times 10^{-7} m to 0.001 m$

No, this transition is not in IR region of the electromagnetic spectrum.
