Abstract:

The metastable state SI in single crystals of orthorhombic Na2FeCN5NO-2M2O sodiumnitroprusside, SNP was investigated by absorption spectroscopy. The development of the spectra with increasing population of SI was monitored and a new band in the red spectral range was assigned to SI. By comparing with density functional theory DFT calculations we were able to assign the band to the electronic transition 2b2 right arrow 7e. In addition we found that very strong holographic light scattering influences the absorption spectra measured with light polarization along the a- or b-axis of the crystals.
