AbstractAbstract
[en] A selective multiphoton photochemical process has been used to enrich nitrogen-14 isotope in methylamine. A separation factor of two has been achieved for irradiation of CH3N14H2/CH3N15H2/NO sample with the P(24) line of the 9.6 μ CO2 laser transition. The threshold laser energy fluence for reaction is roughly 30 joules/cm2. The vibrational isotope shift of methylamine at 9.6 μ region was found to be 12.5 cm-1. The selectivity of the photochemical reaction appears to be limited by the overlap of vibrational-rotational lines of CH3N14H2 and CH3N15H2 molecules due to power broadening under the intense laser field
