Room temperature mid-infrared experiments between 600 and 1600 cm(-1) have been performed on crystalline deoxycytidine as a function of pressure up to about 10 GPa. The wavenumbers of most vibrational modes shift to higher values with increasing pressures except for a mode near 840 cm(-1). Assignments for the observed modes are made on the basis of work published in the literature. Several anomalies are noted near 4.7 GPa, suggesting a phase transition. Our results for deoxycytidine are compared to similar measurements on cytidine.
在高达约10吉帕斯卡的压力下,对结晶脱氧胞苷进行了600至1600厘米⁻¹之间的室温中红外实验。除了840厘米⁻¹附近的一个模式外,大多数振动模式的波数随压力增加而向更高值移动。根据文献中发表的工作对观察到的模式进行了归属。在4.7吉帕斯卡附近发现了几个异常现象,表明发生了相变。将我们关于脱氧胞苷的结果与对胞苷的类似测量结果进行了比较。
