Fluorescence Spectrum Of Quinine

All rights reserved copyright c2008 hitachi high technologies corporation. The fl 6500 fluorescence spectrometer is the optimal system for analyzing samples susceptible to photo bleaching. A variety of processes can result in quenching such as excited state reactions energy transfer complex formation and collisional quenching.

With our new fluorescence spectroscopy instruments your laboratory can generate accurate and reliable fluorescence data featuring continuous wave technology.

Fluorescence spectrum of quinine. What is the quantum yield. The excitation wavelength was 310nm. The fluorescence emission spectrum of quinine sulfate dissolved in 05 m h2so4. Quantum yieldf number of photonsemitted.

It is a form of luminescence. Other applications of fluorescence in safety equipment include marine buoys and road signs which also make use of fluorescent paints. Fluorescent or black light paints tend to be bright in color with yellow green orange and red being common hues.

In most cases the emitted light has a longer wavelength and therefore lower energy than the absorbed radiation. Photo bleaching may be experienced with certain thin coatings and compounds in bioresearch cell biology molecular biology immunology enzymology tissue and protein samples. Che425l fluorescence spectroscopy following absorption a number of vibrational levels of the excited state are populated. Fl 6500 is also excellent for phosphorescence analysis.

Quenching refers to any process which decreases the fluorescence intensity of a given substance. Our team of scientists has experience in all areas of research including life science material science chemical synthesis chromatography analytical and many others. Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. The quantum yield of this molecule is 0546 eaton 1988.
