摘要: From measurements of the J=1→2 rotational transitions methyl acetylene and some its isotopic modifications, moments inertia, IB (in units 10−40 gm cm2), were found for ground vibrational state: CH3CCH, 98.1723; CH3C13CH, 98.2132; C13H3CCH, 100.9193; CH3CC13H, 101.1992; CH3CCD, 107.7234; CD3CCD, 124.5806. The centrifugal distortion constants, DJK, in mc/sec. are 0.161, 0.16, 0.13, 0.14, 0.09, respectively. J=2→3 transition CH3CCH was also measured, constant DJ to be 0.005 Four lines corresponding six excited state v10=1 v9=1 measured interpreted according Nielsen's theory l‐type doubling symmetric tops. calculated structure is: C–H (acetylenic), 1.056A; C≡C, 1.207A; C–C, 1.460A; (methyl), 1....
