Question

The Raman shift, related to force constant k and reduced mass μ, is given by ________

(a) \(\frac{1}{2π}\sqrt{\frac{k}{μ}}\)

(b) \(\frac{1}{2πc}\sqrt{\frac{k}{μ}}\)

(c) \(\frac{1}{2π}\sqrt{\frac{μ}{k}}\)

(d) \(\frac{1}{2πc}\sqrt{\frac{μ}{k}}\)

I got this question by my school teacher while I was bunking the class.

Asked question is from Raman Effect in portion Quantum Physics of Engineering Physics I

Answer 1

Correct option is (b) \(\frac{1}{2πc}\sqrt{\frac{k}{μ}}\)

Explanation: The correct expression for the Raman shift is: \(\frac{1}{2πc}\sqrt{\frac{k}{μ}}\). It is same as the expression for the shift in Infrared Spectroscopy. Thus, they are complementary to each other.
