The Infrared Absorption Spectrum of Methyl Deuteride

摘要: The six fundamental vibrational frequencies of methyl deuteride were observed and the fine structure bands resolved. are v6 = 1156.3, v5 1306.8, v4 1477.1, v3 2205.25, v1 2983.0, v2 3031.0. From bands, moments inertia found to be IA=7.166×10−40 g cm2,IC=5.298×10−40 g cm2 internuclear distances C–H=1.093×10−8 cm,  H–H=1.785×10−8 cm. four previously known methane each this molecule, values five potential constants computed. Three sets consistent agree well with by Dennison Johnston, but other three have either negative or imaginary values. from which these calculated ones take part in a resonance interaction was not included theory. spacings zero branches perpendicular extreme ranges rotation‐vibration factors c...
