Looking at prop-2-yn-1-ol spectrum that was taken from:
Spectrometric identification of organic compounds. Robert M. Silverstein and G. Clayton Bassler. J. Chem. Educ., 1962, 39 (11), p 546. DOI: 10.1021/ed039p546.
Why OH peak is so sharp? And why it is located around 1 ppm? The book does not specify the solvent used.
At the same time if one takes a look at 1H NMR spectrum of the same compound taken on 90 MHz machine in CDCl3. Source: Spectral Database AIST with SDBS No. 74HSP-00-252
- Why the OH peak shifted so much? But it is still as sharp as in other spectrum. Please someone explain such pattern.
