Global analysis of high resolution infrared and rotational spectra of HCCC15N up to 1335 cm21

The rotational spectrum of an enriched sample of HCCC15N was measured from 200 to 1200 GHz. The high-resolution infrared spectrum was also measured from 160 to 11000 cm21. Several thousands of rovibrational and rotational data have been subjected to a global rovibrational analysis for all vibrational levels below 1335 cm21. This work provides accurate parameters for all these levels and a basic set of molecular parameters about the modes 4–7 of HCCC15N. q 2003 Elsevier B.V. All rights reserved.
