Circular dichroism spectroscopy. a The two enantiomers of COTh. b CD spectra of the two enantiomers of COTh in freshly distilled THF solution at 298 k. c, d Time-dependent CD spectral change profiles of the two enantiomers of COTh in freshly distilled THF solution under UV lamp irradiation at 298 k. e, f Time-dependent CD spectral change profiles of the two enantiomers of COTh in freshly distilled THF solution with UV lamp irradiation (black square line) and without UV lamp irradiation (orange circle line), and in the solid state with UV lamp irradiation (blue triangle line) at 298 k, irradiation wavelength: 254 nm. Concentration of the two enantiomers of COTh (−) and COTh ( + ) are 30 and 50 μM, respectively
