HC3N
Cyanoacetylene

Energy levels, transition frequencies and Einstein A coefficients for the vibrational ground state of HC3N were taken from CDMS, version 1 (October 2000). The collisional rates are taken from Faure et al (2016) and were calculated for temperatures in the range from 10 to 300 K including energy levels up to J=37 for collisions with ortho- and para-H2.

The second datafile covers the hyperfine structure of HC3N up to J=20 for temperatures in the 10-100 K range.
