Answer 1

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

Answer 2

Hello there,

● Answer -
λ = 3333 nm lies in IR region.

● Explaination -
For transition of photon from v=0 to v=1 level, energy is given by -
∆E = E1 - E0
hυ = 3/2 hυ0 - 1/2 hυ0
υ = υ0
υ = 9×10^13 /s

Wavelength for transition is calculated by -
λ = c / υ
λ = 3×10^8 / 9×10^13
λ = 3.33×10^-6 m
λ = 3333 nm

Therefore, wavelength of transition from v=0 to v=1 is 3333 nm.

As 700 nm < 3333 nm < 1 mm, this wavelength lies in infrared region of EM spectrum.

Hope this helps you...
