用二极管阵列光谱仪在440-720 nm波长范围和298-200 K温度范围内测量了NO3吸收光谱的温度依赖性。在Cl 2/ClONO 2混合物的351 nm激光光解之后，使用时间分辨的可调谐二极管激光器吸收测量在662 nm处的NO3吸收截面（0-0跃迁的峰值）。NO3在662 nm处的吸收截面在298 K时为（2.23±0.22）x 10-17 cm 2，从298 K到200 K增加了36%（2个误差限，包括估计的系统误差）。这些结果与以前的测量进行了定量比较。
The temperature dependence of the NO3 absorption spectrum was measured over the wavelength range 440-720 nm and temperature range 298—200 K using a diode array spectrometer. The NO3 absorption cross section at 662 nm, the peak of the 0—0 transition, was measured using time resolved tunable diode laser absorption following 351 nm laser photolysis of a CI2/CIONO2 mixture. The NO3 absorption cross section at 662 nm was (2.23±0.22) x 10-17 cm2 at 298 K and increased 36% in going from 298 to 200 K (2 error limits including estimated systematic errors). These results are quantitatively compared with previous measurements.
