Scientific paper

Observations of the cyanopolyyne peak of Taurus Molecular Cloud 1, obtained using a 32-50-GHz double-sideband mixer-receiver on the 45-m telescope at Nobeyama Radio Observatory during June and September 1987 and March 1988, are reported. The data are presented in tables and sample spectra and briefly characterized. All five isotopic species of cyanobutadiyne (HC5N) were detected, with column densities of (6.1-8.0) x 10 to the 11th/sq cm and carbon isotopic ratios similar to those of the solar neighborhood.
