Non-resonant near infrared (λexc = 1064 nm) solid-state FT-Raman spectra were recorded with
a Bruker FT-Raman spectrometer with a spectral resolution of 4 cm–1. As a Raman excitation source, a Nd:YAG laser with
125 mW power at the sample was used at its fundamental frequency.
The Raman light was collected by a liquid nitrogen-cooled Ge detector.
DUV-RR spectroscopy experiments were performed with the help of a
UV Raman setup (Horiba/Jobin-Yvon) equipped with a liquid N2-cooled CCD detector. The DUV-excitation wavelengths λexc = 257 nm and λexc = 244 nm were derived
from an intracavity frequency doubled argon-ion laser (Coherent Inc.)
and focused on the sample (257 nm: PL =
2.20 mW; 244 nm: PL = 0.22 mW) with an
objective lens, and the spectral resolution was 5 cm–1.
The UV–vis absorption spectra of all the measured
sample solutions were recorded with a Carry 5000 UV–vis–NIR
spectrometer (Varian).
