MOLECULAR-STRUCTURES OF GAS-PHASE POLYATOMIC-MOLECULES DETERMINED BY SPECTROSCOPIC METHODS

Spectroscopic data related to the structures of polyatomic molecules in the gas phase have been reviewed, critically evaluated, and compiled. All reported bond distances and angles have been classified as equilibrium (re), average (rz), substitution (rs), or effective (ro) parameters, and have been given a quality rating which is a measure of the parameter uncertainty. The surveyed literature includes work from all of the areas of gas‐phase spectroscopy from which precise quantitative structural information can be derived. Introductory material includes definitions of the various types of parameters and a description of the evaluation procedure. © 1979, American Institute of Physics for the National Institute of Standards and Technology.
