✦ Synopsis
Contracted CI calculations, based on CAS SCF reference wavefunctions, are reported for the lowest excited states of HMn(CO), and Fe(C0) 5. The results are used to discuss the photochemical reactions of these organometallics.

CASPT2 calculations based on CASSCF reference wavefunctions, using large atomic natural orbital basis sets, are reported for the lowest excited states of H2Fe(CO) 4. The excitation energies obtained with this accurate method are compared to the values from multireference contracted CI calculations b
When an unfocused laser beam with narrow linewidth whose frequency matches exactly an atomic transition line of the Fe atom was passed through a gas mixture containing Fe(CO)5, atomic emissions from the state-selected excited state of Fe atoms were observed. The power dependence of the emission inte
## Abstract Chemical shift anisotropies and spin‐lattice relaxation times, __T__~1~, were determined for bridging and terminal carbonyls in __c's__ and __trans__ isomers of [(η^5^‐C~5~H~5~)~2~Fe~2~(CO) ~2~(μ~2~‐CO)~2~]. The relaxation path of the ^13^CO resonances occurs through the dipolar interac
