Chiroptical properties of an isolated pyridine chromophore: the circular dichroism spectra in the near ultraviolet region of (–)-(R)-2-(1,2,2-trimethylpropyl)pyridine

The circular dichroism spectra of (–)-(R)-2-(1,2,2-trimethylpropyl)pyridine, under various conditions of solvent and temperature, are reported. The results are consistent with the presence of three electronic transitions (two n→π* and one π→π* excitations) in the spectral range examined (300–230 nm).
