Molecular Line Parameters in the HITRAN 2008 database for Hydrogen cyanide HCN
Intensities in log [cm/molecule] at 296 K vs wavenumber (cm-1).
The labels at right indicate the HITRAN molecule number and the chemical formula.
The most abundant isotopologue is plotted in black, 2nd abundance in red, 3rd in blue, 4th in orange, 5th in green.
For species with more than 6 isotopologues, the sequence of colors is repeated: 6th is black, 7th is red, 8th is blue, 9th is orange and 10th is green.
