Comments: Two single-mode diode lasers were used to record high-resolution absorption spectra of NO2 (dilute in Ar) 
near 670.2 and 394.5 nm over a range of temperatures (296 to 774 K) and total pressures (2.4 × 10-2 to 1 atm). 
Variations of the spectral absorption coefficients with temperature and pressure were determined from measured spectra.
