摘要
A linelist of vibration-rotation transitions for C-13 substituted HCN is presented. The linelist is constructed using known experimental levels where available, calculated levels and ab initio line intensities originally calculated for the major isotopologue. Synthetic spectra are generated and compared with observations for cool carbon star WZ Cas. It is suggested that high resolution HCN spectra recorded near 14 mu m should be particularly sensitive to the C-13-C-12 ratio.
