Excitation and emission spectra for

The corrected excitation and emission spectra for quinine sulfate from previous work (17) and from a round-robin exercise (11) are given In Figure 1. The coefficients of variation are also given at each point to Indicate the amount of agreement In measured values from the ten laboratories participating In the round-robin exercise.

Excitation and emission spectra for the flavoprotein preparation was obtained in 100 mM acetic acid using an Aminco Bowman Spectrofluorometer. 

A fluorescence emission spectrum is a record of fluorescence intensity vs wavelength for a constant intensity of exciting light. Excitation and emission spectra for a flavin and for the indole ring of tryptophan are both given in Fig. 23-13. The heights of the... 

Corrections of the fluorescence excitation and emission spectra for the optical densities (inner filter effect) yield an increase in the intensities without inducing any shift in any of the maxima. This is true for all recorded spectra. At the optical densities we are suggesting, you may find that these corrections are not significant and even not necessary for all fluorophores but ethidium bromide. Its intensity increases without any modification in the peak position. 

Based on the excitation and emission spectra for compound Y shown above, what excitation and emission wavelengths should be chosen to maximize the measured fluorescence intensity ... 

Fig. 45. Excitation and emission spectra of intermediate II at - 30°C after elution from Sephadex LH-20 at — 25°C. For comparaison, the normalized excitation and emission spectra for FMN are given under the same conditions. The excitation spectra for intermediate II and FMN emission were monitored at 485 and 525 nm, respectively. The emission spectra for intermediate II and FMN were obtained via excitation at 370 and 450 nm, respectively. From Balny and Hastings (1975). Reprinted with permission of Biochemistry.

Figure 4 shows the excitation and emission spectra for reference standard fluorouracil from 250 to 600 nm (6). The spectra, measured in a methanol solution of fluorouracil (1.0 mg/ml) using a Farrand MK-1 Spectro-fluorometer, showed one excitation peak at 315 nm and one emission peak at 391 nm. 

The excitation and emission spectra for levallorphan tartrate (1 mg/ml of methanol) is shown in Figure 4 (6). Two maxima appear in the excitation spectrum at 306 nm. When O.IN HCl is used as the solvent the maxima occur at the same wavelengths but a 5 fold increase in sensitivity is obtained. 

The excitation and emission spectra for methy-prylon (1 mg/ml methanol) are shown In Figure 4 (4) The excitation spectrum exhibits a broad maximum at about 302 nm and a shoulder about 239 nm. The emission spectrum has one maximum about 396 nm.
