After the UV irradiation of suspensions of barbiturate sodium salts in paraffin oil the IR spectra revealed two IR absorption bands at ca. 2170 and 2250 cm-1. The effects of different conditions of the photochemical process and the addition of nucleophilic reagents after irradiation on the intensity of these bands were studied. The origin of 2170 cm-1 band was interpreted in terms of the isocyanate intermediate which is formed after the pyrimidine ring opening.
在对巴比妥酸钠盐在石蜡油中的悬浮液进行紫外线照射后，红外光谱显示在约2170和2250 cm⁻¹处有两个红外吸收带。研究了光化学过程的不同条件以及照射后添加亲核试剂对这些吸收带强度的影响。2170 cm⁻¹吸收带的起源是根据嘧啶环开环后形成的异氰酸酯中间体来解释的。
