In no sense have the articles been simply literature surveys, although in some cases theymay havealsofulfilled thatpurpose. IntheintroductiontoVolume1ofthisseries,thefoundingeditors,J.N.Pitts, G.S.HammondandW.A.Noyes,Jr.noteddevelopmentsinabriefspanofprior years that were important for progress in photochemistry: flash photolysis, nuclearmagneticresonance,andelectronspinresonance.Aquarterofacentury later, in Volume 14 (1988), the editors noted that since then two developments hadbeenofprimesignificance:theemergenceofthelaserfromanesotericpos- sibilitytoanimportantlightsource,andtheevolutionofcomputerstomicrocom- puters in common laboratory use of data acquisition. These developments strongly influenced research on the dynamic behavior of the excited state and other transients. With the increased sophistication in experiment and interpretation since that time,photochemistshavemadesubstantialprogressinachievingthefundamental objectiveofphotochemistry:elucidationofthedetailedhistoryofamoleculethat absorbs radiation. The scope of this objectiveis so broad and the systems to be studiedaresomanythatthereislittledangerofexhustingthesubject.Wehope thatthisserieswillreflectthefrontiersofphotochemistryastheydevelopinthe future. vii viii CONTRIBUTORS As readers will see from the Senior Editor’s Statement on the nextpage, the EditorsoftheAdvancesSeriesarechangingwithVolume28.Asalwayswewish tohear fromour readers in ourattempt tokeep the series current and useful. DouglasC.Neckers BowlingGreen,Ohio,USA Gu¨nthervonBu¨nau Siegen,Germany WilliamS.Jenks Ames,Iowa,USA SENIOR EDITOR’S STATEMENT With this Volume we note a change in Editors. Gu¨nther von Bu¨nau, who has recentlyretiredfromtheUniversityofSiegenhaschosenthistimetoalso‘retire’ fromtheEditorialBoard ofAdvances.Gu¨ntherhas beenastrongcontributorto theSeriesaswehavecollectivelyworkedtomakeAdvancesahelpfulliterature asset. I will really miss working with him and wish him thevery best in retire- ment. However with change comes opportunity, and we are delighted to welcome Thomas Wolff who will join us with Volume 28 to our editorial triumvirate. Professor Wolff took his degree at the University of Go¨ttirgen under the super- vision of Albert Weller and Karl-Heinz Grellmann. After joining the group of Gu¨nther von Bu¨nau and then finishing his habilitation he became Professor of Physical Chemistry at the University of Siegen. In 1993 he moved to the Tech- nicalUniversityofDresdenasaProfessorattheInstituteofPhysicalChemistry. Hisresearchinterestslayintheregionwherephotochemistry,colloidchemistry, and polymer chemistry meet, that is, macroscopic propetries of collid systems that can be switched via photochemical reactionsof solubilizedmolecules. In the best of American traditions, we offer Gu¨nther our sincere congratula- tionsonajobwelldoneandthankhimforhisverymanyexcellentcontributions tothe series.
