Vibrational Frequency

  1. Nov 8, 2005 #1
    The mass of the deuterium molecule is twice that of the hydrogen molecule. If the vibrational frequency of helium is 1.34x10^14 Hz, what is the vibrational frequncy of deuterium, assyming that the spring constant of attracting forces is the same for the two species? Answer in units of Hz.

    frequency: w=square root of k/m


    Please help thank you.

    You have correctly used: [tex]\omega = 2\pi f = \sqrt{\frac{k}{m}[/tex]

    So what is [tex]f_{1}/f_{2}[/tex]?
