论文摘要
Rovibrational bands spectra of three $ν_{20}$, $ν_7$ and $ν_{19}$ bands of 1, 3, 5 -- trioxane (H$_2$CO)$_3$ were recorded in the 50--650 cm$^{-1}$ range using a long path absorption cell coupled to a high resolution Fourier transform spectrometer and synchrotron radiation at Soleil同步子的Ailes光束线。超过16000行的DRM分配了$ 0.17 \ times10^{ - 3} $ cm $^{ - 1} $。使用两种不同的形式主义（Tensorial和Watson）来得出三个频段的准确旋转和四分之一的参数，这是Coriolis参数的精确确定和$ Q _+$ $ $ l- $ l- $ l- $ l- $ l- $ l- $ l- $ l- $ l- $加倍常数，$ν_{20}} $和$ν_{19} $ n {19} $ perpendicular Bands均可获得。最后，将两种形式主义之间的每组光谱参数进行比较和讨论。
Rovibrational bands spectra of three $ν_{20}$, $ν_7$ and $ν_{19}$ bands of 1, 3, 5 -- trioxane (H$_2$CO)$_3$ were recorded in the 50--650 cm$^{-1}$ range using a long path absorption cell coupled to a high resolution Fourier transform spectrometer and synchrotron radiation at the AILES beamline of the SOLEIL synchrotron. More than 16000 lines were assigned with a dRMS better than $0.17\times10^{-3}$ cm$^{-1}$. Two different formalisms (tensorial and Watson) were used to derive accurate rotational and quartic parameters for the three bands and for the first time, a precise determination of Coriolis parameter and $q_+$ $l-$doubling constant for both $ν_{20}$ and $ν_{19}$ perpendicular bands was obtained. Last, each set of spectroscopic parameters is compared and discussed between both formalisms.
