Study of IR spectra of thiacalix[4]arene with carboxyl and adamantyl groups [PDF]

E3S Web of Conferences, 2021
The IR spectra of p-(3-carboxy-1-adamantyl)thiacalix[4]arene (1) were studied. IR spectra of compound 1 do not contain bands of free hydroxyl groups. The νOH value at 3377 cm-1 signifies the formation of an intramolecular H-bond along the lower edge of ...
