ABSTRACT
The following is a synopsis of the German Diving Accident Guidelines, which may be found on www.gtuem.org in German and English. It is the second revision of a guideline initially published in 2002. The first version was reviewed in 2005 and then revised and updated in 2008. It is valid until October 2011 when the next revision is scheduled. Each version was developed by a group of experts and was then presented to a consensus conference organised by the GTÜM. An independent international steering committee (jury) at the conference created the final document. This is the first version published in both English and German. The extensive reference list used in preparing this document is available on the GTÜM website.
ABSTRACT
A bridged d0 zirconocene dichloride is reported as a first group 4 metal complex possessing rare long-lived ligand-to-metal charge transfer (LMCT) excited states with high emission yields and excited-state lifetimes in fluid solutions (e.g., PhiLUM = 0.41 and tau = 17.6 micros in 1,2-dichlorobenzene at 20 degrees C). The basic emission parameters PhiLUM and tau are shown to be extremely solvent-dependent in fluids at room temperature. The first principle dependences of LMCT emission parameters on solvent properties are revealed with use of the target complex. For fluid solutions, the linear correlation between PhiLUM and tau is reported, thus suggesting that a solvent determines the rate constant for nonradiative decay, knr.
