考察了KMS-a和KMS-b的固态、液态和熔融态红外光谱,并结合质谱、核磁共振谱的结果,确认了这两个熔点不同的结晶物是结构式相同而晶形不同的化合物。
The solid-state, liquid and melt infrared spectra of KMS-a and KMS-b were investigated. The results of mass spectrometry and nuclear magnetic resonance showed that the two crystals with different melting points were of the same structure and different crystal forms.
