SUMMARY
The discussion centers on calculating the force constant for gaseous 14N16O using the simple harmonic oscillator model. The fundamental vibrational frequency is given as 1904 cm-1, which is identified as a wavenumber rather than a frequency in Hz. The reduced mass (u) is calculated as 1.24e-26 kg/molecule, leading to a force constant (K) of 1.77e-22 kg m2. The conversion from wavenumber to frequency is clarified as necessary for accurate calculations.
