N2  - The c.d. spectra of &#945;,&#946;-unsaturated ketones through the n &#8594; &#960;* absorption region are, in general, better resolved than the corresponding ultraviolet spectra and are free of overlap from neighbouring transitions. In consequence, the nature of the solvent-induced blue shift is more clearly discernible in circular dichroism. That part of the blue shift which is ascribable to hydrogen bonding is shown to result from a redistribution of intensity between vibrational sub-bands rather than a change in energy of the n &#8594; &#960;* band as a whole.
