The stability constants I( of the 1:l host to guest complexes formed between eight phenols and the cyclis tetramer, cyclotetr chromotropylene, 't in an aqueous solution at pD 7.0 at 25 C were determined b H nmr spectroscopy. They vary from -0 (p-sodium sulfonatophenol) to 400 M \_y (pnitrophenol).

Abstract
Lanthanide salt induced shifts in the NMR spectra of phenols are found to increase in basic media. The empirical relationships governing the interaction of phenolic hydroxyl groups, reported earlier, still apply.

The interaction of caffeine and theophylline with sodium benzoate and sodium salicylate has been studied in deuterium oxide at 35°C by measnring the aromatic salt-induced changes in the chemical shifts of the N-methyl protons. Taking into account the self-association of the N-methylxanthines, on the
## Abstract Fast‐atom‐bombardment (FAB) mass spectra have been used to establish or confirm the nature of the yellow‐product and open‐chain forms of thiamine produced in the presence of excess (5 mol‐equivb.) of strong base. Time‐dependent changes in ^1^H‐NMR spectra show that the rates of disappea
## Abstract ^1^H and ^13^C NMR assignments of sodium chenodeoxycholate in aqueous solution were obtained for three different bile salt concentrations. ^1^H and ^13^C NMR chemical shifts of sodium chenodeoxycholate and deoxycholate show slight concentration dependence due to micelle formation. Oppos
