Circular dichroism

Initial calculations of the rotational strengths for the first two transitions of (S)-(-)-2-methyl-1-butanol have been carried out using an independent systems theory approach. The theoretical rotational strengths are computed using three different values of bond polarizability. These calculated rotational strengths are compared to the experimentally measured values. The assignment of the transitions does not depend on which polarizability is used. The results are consistent with the assignment of the first two electronic transitions in simple alcohols as n-sigma OH*, and n-sigma CO*.
