用外差频率技术测量了N2 O在4300-4800 cm− 1范围内0002-0000、2001 - 0000和1201-0000波段的39条谱线的绝对频率。每一条线都是在多普勒限制吸收中测量的，用色心激光器作为N2 O的可调谐探针，两个稳定的CO2激光器作为参考频率。新的振转常数已被安装到这些测量。给出了计算的跃迁频率表，估计的绝对不确定度小至10−4cm−1。已经测量了四条线的压力变化，其值在0至−2 MHz/kPa（0至−0.2 MHz/Torr）的范围内。
The absolute frequencies of 39 lines in the 0002-0000, 2001-0000, and 1201-0000 bands of N2O in the range 4300–4800 cm−1have been measured by heterodyne frequency techniques. The lines were each measured in Doppler-limited absorption, with a color-center laser as a tunable probe of the N2O and two stabilized CO2lasers as reference frequencies. New rovibrational constants have been fitted to these measurements. Tables of calculated transition frequencies are given, with estimated absolute uncertainties as small as 10−4cm−1. The pressure shifts of four lines have been measured, and the values fall within the range of 0 to −2 MHz/kPa (0 to −0.2 MHz/Torr).
