K.-M. Marstokk,Harald Møllendal +1 more
TL;DR: In this paper, the microwave spectra of 13 CH 2 OH-CHO, CH 2 O-13 CHO, CH O-CH 18 O and 13 CH O were used in combination with previously published data on other monosubstituted glycolaldehydes to determine the substitution structure of the molecule.

Influence of vibrations on molecular structure determinations iii. inertial defects
TL;DR: In this paper, the relationship between various types of moments of inertia and vibration is developed from general theory, with emphasis on the qualitative physical features and the quantities which may be calculated without knowledge of anharmonic force constants.
