초록
Phenol과 각 종 Dimethylaniline(DMA)간의 수소결합을 Infrared Spectrophotometer로 연구하였다. 일반으로 DMA는 n-donor 및 ${\pi}$-donor의 2중 역활을 하나 주로 n-donor로 작용하며 phenol의 O-H stretching frequency의 shift(${\Delta}{\nu}$)는 DMA의 basicity에 비례하였고 (${\Delta}{\nu}$) 와 Hammett의 σcontant사이에는 linearity가 성립함을 알았다.
Intermolecular hydrogen-bonding between phenol and N,N'-dimethylanilines (DMA) has been studied by infrared spectrophotometry. Results show that DMA acts as n-and ${\pi}$-donor although n-complex predominates. O-H stretching frequency shifts (${\Delta}{\nu}$) were proportional to basicitys of DMA and excellent linearity was observed between ${\Delta}{\nu}$ and the Hammett substituent constant, ${\sigma}$.
