Resonance Raman Analysis of Charge-Transfer Reorganization Energies in Covalent Dicyanoethylene-azaadamantane

Resonance Raman cross sections have been measured for a covalent electron donor-acceptor substituted aza-adamantane. Excitation near the maximum of the strong charge-transfer absorption results in resonance enhancement of a number of Raman fundamentals, overtones, and combination bands. The reorganization energy in each molecular mode and the solvent contribution to the electronic linewidth are determined through quantitative modeling of the absorption, Raman, and fluorescence spectra, which are sensitive to solvent dynamics on different time scales. The results suggest that the solvent-induced broadening in methanol has components that fluctuate on a wide range of timescales.link_to_subscribed_fulltex

Canada falls short on safeguarding its drug supply

The influence of the structure of the triplet excited state of benzophenone (bp) and decafluorobenzophenone (dfbp) on the reactivity towards hydrogen abstraction was studied by time-resolved resonance Raman spectroscopy. The resonance Raman spectra and Raman excitation profiles were recorded for both the triplet excited state and the ketyl radical. Vibrational spectral assignments were made for all the intermediate states. Based on the analysis of the spectra, it was concluded that the enhanced reactivity towards hydrogen atom abstraction of dfbp over bp is due to (a) the non-planar structure of the triplet excited state of dfbp, thus increasing the accessibility for the CO group, and (b) the highly polarized and electrophilic nature of the CO group in the triplet excited state of dfbp

Does structured clinical supervision during psychosocial intervention education enhance outcome for mental health nurses and the service users they work with?

This study aimed to assess whether clinical supervision provided by workplace-based supervisors can enhance outcomes for mental health nurses attending a psychosocial intervention education programme and the service users whom they work with. A quasi-experimental controlled design was used. The main outcome measure was student knowledge and attitudes towards individuals with psychosis and their caregivers. Secondary outcome measures for service users included the KGV (M) symptom scale and the Social Functioning Scale. Students in the experimental group demonstrated a significant increase in knowledge of psychological interventions compared with the control group. Service users seen by the students in the experimental group showed significantly greater reductions in positive psychotic symptoms and total symptoms compared with those seen by students in the control group. Workplace clinical supervision may offer additional benefit to nurses attending psychosocial intervention courses. Further research adopting more robust designs is required to support these tentative findings
