Unformatted text preview: the wavelength of the absorbed photons,
the reduced mass, and the force constant.
With ̃ ̃
. , the vibration frequency is
The photon wavelength is
The force constant k can be determined from
√ ̃ This gives . The period of vibration is
. The reduced mass is ̃ . 10. Oscillator. When carbon monoxide, 12C16O, is bound to the muscle-tissue protein myoglobin, the
vibrational frequency of its stretching mode is 1945 cm-1. Compute the frequency of the same
vibrational transition in 13C16O, assuming the force constant is not affected by the isotope change.
The wavenumber can be computed via
̃ √ ̃ √ The reduced masses are ̃√
for for 13C16O. Fro...
