Energy transfer is the process by which energy is relocated from one system to another, for example, through the transfer of heat, work or mass transfer. In chemistry, the affect of atomic or molecular composition on energy transfer is studied, examples of which include energy transfer through ...
Unit 3 Lesson 2 Energy Transfer Where does radiation occur on Earth? The sun is almost 150 million km away from Earth, but it is the major source of energy for processes on Earth. Solar radiation is partly reflected and scattered by Earth’s atmosphere. However, some solar radiation is abs...
Radiation and collisional energy transfer among the A2Πi and X2∑+ states of CN Laser-photolysis–laser-induced-fluorescence methods are used to characterize the collisional energy transfer between CN (A2Πi) and (X2∑+) states and to ... Y Huang,R Lu,JB Halpern - 《Applied Optics》 ...
Define Energy transfer. Energy transfer synonyms, Energy transfer pronunciation, Energy transfer translation, English dictionary definition of Energy transfer. n. pl. en·er·gies 1. The capacity for work or vigorous activity: Who has the energy to climb
Linear energy transfer (LET) (Fig. 14-83) LET is defined as the ratio of energy transferred by a charged particle (dElocal) to the target atoms along its path through tissue (dx). In other words, LET is a measure of the density of ionizations along a radiation beam. ...

The energy transfer step may occur by resonance energy transfer, generally from the first excited singlet state (S1), or by exchange energy transfer, generally from the first excited triplet state (T1).53 In either case, efficient energy transfer requires that the excitation energy of the photose...
R Gaza,EG Yukihara,SWS Mckeever - 《Radiation Measurements》 被引量: 55发表: 2004年 Investigation of chemical kinetics and energy transfer in a pulsed microwave H2/CH4 plasma We present a modelling study of pulsed H2/CH4 microwave plasmas obtained under moderate pressure discharge conditions in ...
In some of these cases the energy transfer process was also studied in solution (where the quenching process is diffusion controlled) for comparison purposes. The main conclusion was that on cellulose the quenching process has a static nature. Both direct absorption of the excitation radiation by ...
20. According to the variation of the luminescence efficiency, the intramolecular energy transfer and relaxation processes of the complexes were studied. 研究了配合物的分子内能量传递和弛豫过程,配体最低三重态能级与稀土离子共振能级之间的能级差是否匹配是配体敏化中心离子发光的关键因素。
