Via intense ps-excitation of the OH-stretching vibration of ethanol diluted in CCl4 we succeed in spectral hole burning within the inhomogeneously broadened oligomer band. The lifetime of the transient hole and the v=1-level of the OH-stetch of associated ethanol molecules are determined to be about 1.2 and 1.7 ps, respectively. Further dynamical features are discussed which give evidence for energy migration within the H-bonded ethanol chains and subsequent breaking of the oligomers into shorter fragments.

ABSTRACTIn the context of spectral-hole burning experiments in 4H- and 6H-SiC doped with vanadium the energy positions of the V4+/5+ level in both polytypes were determined in order to resolve discrepancies in literature. From these numbers the band offset of 6H/4H-SiC is calculated by using the Langer-Heinrich rule, and found to be of staggered type II. Furthermore the experiments show that thermally stable electronic traps exist in both polytypes at room temperature and considerably above, which may result in longtime transient shifts of electronic properties.
