Abstract
The collision-induced absorption fundamental band of N2 has been investigated in the 2100–2600 cm−1 spectral region. Laboratory measurements have been undertaken over the temperature range 193–297 K. Binary-absorption coefficients for N2 absorption induced by collisions with N2 and O2 are reported and compared with N2 temperature-dependent continua from atmospheric measurements.Keywords
