A novel method is suggested to measure the absolute excited singlet-sin&t absorption spectrum of rhodamine by bleachinp completely the solution. The motar decadic estinction coefficient of the excited state fe = 4.8 X IO4 liter mole-' cm-" at 440 nmj is estimated directly from the #&au-like absorpti
An absorption spectrum attributable to the transition from the first excited singlet state to higher singlet states (S' Q--S transition) of pgrene in soIution has been observed by the flash method.
We propose a new method of alpha (a)-ray measurement that detects helium atoms with a Quadrupole Mass Spectrometer (QMS). A demonstration is undertaken with a plastic-covered 241 Am a-emitting source to detect a-rays stopped in the capsule. We successfully detect helium atoms that diffuse out of the
