Observation of the photo-excited state of [CoIII(en)3]3+by picosecond time-resolved XAFS

Time Resolved Excited State Photo-Engineering

This thesis concerns the development and application of time resolved fluorescence which yield new and detailed information on molecular order and motion in both isotropic and ordered systems. Polarised fluorescence studies involve the photoselection of a non-equilibrium distribution of excited state probe orientations whose relaxation is monitored by time resolved fluorescence anisotropy. Chap...

Time-Resolved Measurement of Excited-State Populations

Introduction The absorption of light is the most common method for the investigation of the energy levels and transfer processes of atomic and molecular systems. The measurement of the ground-state absorption (GSA) provides information on the energy level scheme. If the density of the atoms or molecules in the stable ground state is known then the cross sections of the GSA transitions can be ca...

The nonradiative decay of the allyl radical excited B 2 A 1 state studied by picosecond time-resolved photoelectron spectroscopy

Time-resolved excited state dynamics of a cyanine dye

X Ž . The photophysics and isomerization dynamics in the excited state of a cyanine dye, 3,3 -di 3-sulfopropyl -thiacyanine triethylaminium salt was investigated. Using the femotosecond time-resolved fluorescence up-conversion technique, wavelength-dependent fluorescence dynamics was observed and the theoretical prediction of the dual fluorescence behavior was vindicated. The results were expla...

the effects of time planning and task complexity on accuracy of narrative task performance

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...
