| Outline of Final Research Achievements |
To demonstrate the usefulness of isotopomer (isotopic molecular species) abundance ratio measurement using rotational coherence, experiments and simulations were carried out for N2O molecules. The experiments using two femtosecond-laser pulses showed that the rotational Raman spectrum of N2O molecule can be obtained by Fourier transforming the amplitude of the ion yield. The simulations using molecular rotational wave packet calculations showed that the rotational Raman spectrum obtained by Fourier transforming the variation of the ion yield is almost unaffected by the angular dependence of N2O ionization, indicating that the method is robust and reliable against variations in laser irradiation conditions.
