The current coupled fit encompasses well over 12000 transition frequencies and delivers precise vibrational energy information entirely on the basis of many fitted perturbations in rotational transitions. The present work was used to further refine the features for identifying perturbations built into the AABS package for Assignment and Analysis of Broadband Spectra., {\bf 233}, 231 (2005).} en_US dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title PERTURBATIONS AND VIBRATIONAL ENERGIES IN ACRYLONITRILE FROM GLOBAL ANALYSIS OF ITS MM-WAVE TO THZ ROTATIONAL SPECTRUM en_US dc.type Article en_US dc.type Image en_US dc.type Presentation en_US
