[1]对臭氧的三个基本原理进行了高分辨率傅里叶变换红外测量。共记录了16个光谱，包括室温和200K下纯臭氧以及氧气和氮气加宽的臭氧，重点放在样品制备的质量保证以及防止仪器和提取错误上。确定了谱线位置、谱线强度和加压加宽的半宽度。对谱线位置和谱线强度进行了量子力学分析，得到了改进的分子常数。对于不同结合的子带集合，计算了各个压力展宽参数和温度指数，并将其表示为m量子数中的多项式。对许多强转变的谱线强度和压力展宽的精度都达到了2%以上。新数据适用于逐行光谱数据库的更新。
[1] High-resolution Fourier transform infrared measurements of the three ozone fundamentals have been performed. A total of 16 spectra have been recorded, including pure as well as oxygen- and nitrogen-broadened ozone at room temperature and 200 K. Focus was set on quality assurance for sample preparation and on prevention of instrumental and retrieval errors. Line positions, line strengths and pressure-broadened half widths have been determined. A quantum mechanical analysis of line positions and line strengths was performed, and improved molecular constants were obtained. Individual pressure-broadening parameters and temperature exponents were calculated and represented as polynomials in the m quantum number for differently binned sets of subbands. Accuracies of better than 2% were achieved for both line strengths and pressure broadening of many strong transitions. The new data are suited for update of line-by-line spectroscopic databases.
