VizieR Online Data Catalog: HC5N vibrationally excited states (Yamada+,
Abstract
The rotational spectrum of the semistable HC5N molecule ha investigated in the millimeter-wave region for eight excited bending states which lie below 500cm-1, namely v11=1, 2, 3, and 4, v10=1, v9=1, (v10=1, v11=1), and (v10=1, v11=2). Transitions up to J=101-100 were measured, reaching a frequency as high as 270GHz. The set of spectroscopic constants determined in the present work makes it possible to predict much improved rest frequencies of millimeter-wave lines produced by vibrationally excited HC5N in hot core molecular sources and circumstellar shells. The Tables list the measured frequencies and the corresponding residuals of the least-squares analyses of J+1<--J transitions, with J in the range 8-100, which occur in the centimeter- and millimeter-wave regions.
