- Summary
- 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 CH/sub 3/N/sup 14/H/sub 2//CH/sub 3/N/sup 15/H/sub 2//NO sample with the P(24) line of the 9.6 ..mu.. CO/sub 2/ laser transition. The threshold laser energy fluence for reaction is roughly 30 joules/cm/sup 2/. The vibrational isotope shift of methylamine at 9.6 ..mu.. region was found to be 12.5 cm/sup -1/. The selectivity of the photochemical reaction appears to be limited by the overlap of vibrational-rotational lines of CH/sub 3/N/sup 14/H/sub 2/ and CH/sub 3/N/sup 15/H/sub 2/ molecules due to power broadening under the intense laser field.
