Abstract :
We investigate the time-dependent harmonic emissions from nonadiabatically aligned molecules. It is shown that the spectral minimum position depends linearly on 1/ <;cos2 θ>. This relation indicates the possibility of tracing molecular rotational dynamics by measuring the spectral minima.
