Abstract
The high resolution infrared spectrum of methylamine has been analyzed in the 40-720 cmâ1 region (the ν15â¯=â¯2â1 hot and ν15â¯=â¯2â0 overtone bands) with a resolution of 0.00125 cmâ1. More than 14,400 rovibrational transitions (out of 133,000 spectral lines) for 0â¯â¤â¯Kâ¯â¤â¯13 and Kâ¯â¤â¯Jâ¯â¤â¯40 have been assigned using an original Loomis-Wood program dedicated to methylamine. A global fit of the torsional hot and overtone transitions has been carried out. The assigned transitions were fit to a single state model based on the group theoretical formalism of Hougen and Ohashi, which for the second torsional state seems to be at the limit of applicability. The standard deviation of the fit with Kâ¯â¤â¯11 and Jâ¯â¤â¯40 to 94 parameters was 0.006 cmâ1.
