| Summary: | <p>I. The infra-red and Raman spectra of Mn(CO)<sub>5</sub>Br as
both solid and CH<sub>2</sub>Cl<sub>2</sub> solution from 50 to 2150 cm<sup>-1</sup>
are presented for the normal isotopic compound, and
the <sup>13</sup>CO and C<sup>18</sup>O substituted molecules. The observed
bands are assigned, and the force constants and compliance
constants of a general quadratic potential field
are calculated using the FG method of Wilson, Decius,
and Cross.</p>
<p>II. The infra-red and Raman spectra of both Mn<sub>2</sub>(<sup>12</sup>CO)<sub>10</sub>
and Mn<sub>2</sub>(<sup>13</sup>CO)<sub>10</sub> as solids and in CH<sub>2</sub>Cl<sub>2</sub>
solutions from 50 to 2150 cm<sup>-1</sup> are presented and are assigned. Potential
constants are calculated using values transferred
from the Mn(CO)<sub>5</sub>Br calculations. Special attention is
paid to splitting interactions across the Mn--Mn bond
and to the Mn--Mn stretching potential constants.</p>
<p>III. Raman intensities and the electronic absorption spectrum
of M(CO)<sub>5</sub>X<sup>n-</sup> compounds are presented and discussed.</p> |
