Abstract: Using a tunable diode laser spectrometer 53 (N2O)-N-14-O-16 overtone absorption lines have been detected in the range between 11,233 and 11,283 cm(-1) (886-890 nm), with estimated strengths ranging around 10-27-10(-28) cm/molecule. 9 new lines have been found. They have been measured by utilizing commercial AlGaAs/GaAs laser diodes through the wavelength modulation spectroscopy and the 2nd harmonic detection techniques. Self-broadening coefficients have been obtained for 13 of these lines for the first time. Refined molecular parameters have been achieved for this overtone band.
