Abstract
Abstract The molecular structure of isobutane in the gas phase was investigated by combining electron diffraction data with microwave spectroscopic rotational constants of Lide. The analysis indicated that the tertiary C-H distance ( r g = 1.122±0.006 A) was substantially longer than the average methyl C-H distance ( r g = 1.113±0.002 A). Other structural parameters obtained were: r g (C-C) = 1.535±0.001 A, ∠CCC = 110.8±0.2°, and the average ∠CCH (methyl) = 111.4±0.2°.
