Abstract
The line broadening and shift coefficients of the absorption lines of the 15N18O molecule induced by air pressure in the region of 5200 – 5500 cm-1 were measured for the first time. The value of the broadening coefficients for transitions in the 3-0 band was about 0.06 cm-1/atm and was in a good agreement with the values of the broadening coefficients of the 15N16O molecule from the HITRAN database. The line shift coefficients by air pressure lie in the range of 0.005–0.01 cm-1/atm.
