拉曼光谱和红外光谱的有限温度效应确定固体分子氢的晶体结构相III

Anhamonic finite temperature effects on the Raman and Infrared spectra to determine the crystal structure phase III of solid molecular hydrogen

Ranber Singh, Sam Azadi, Thomas D. Kühne

摘要:

我们目前的拉曼光谱和红外光谱的理论计算,以及在零和有限的温度下的电子性质,以阐明固体分子氢的第III相的晶体结构。我们发现,非调和有限温度是特别重要的,定性地影响的主要结论。虽然P6 $_3$ /m在核基态是最有可能的第三相的候选者,在有限的温度下,C2/c结构似乎更合适。

英文摘要:

We present theoretical calculations of the Raman and IR spectra, as well as electronic properties at zero and finite temperature to elucidate the crystal structure of phase III of solid molecular hydrogen. We find that anharmonic finite temperature are particularly important and qualitatively influences the main conclusions. While P6$_3$/m is the most likely candidate for phase III at the nuclear ground state, at finite temperature the C2/c structure appears to be more suitable.
