The spectroscopic study of intramolecular hydrogen bonds of a large nu!nber of compounds was developed by Wulf et al (1). They showed that the change in frequency of vibration occurs at about 7000 cm-l (in wave-number units) corresponding essentially to th? stretching of O-H and N-H bonds in molecul

## Abstract The solvent effect on a nucleophilic substitution reaction of 2‐ and 4‐chloro‐3,5‐dinitrobenzotrifluoride with substituted anilines was studied in methanol, acetonitrile, and toluene at 25Β°C. This reaction is of second order, except 2‐chloro‐3,5‐dinitrobenzotrifluoride in toluene shows
