Which of the following is true about fluorescence?
a)The excitation wavelength of a fluorescent particle is lower in energy than the emission wavelength
b)The excitation wavelength of a fluorescent particle is higher in energy than the emission wavelength
c)Both excitation wavelength and emission wavelength for a fluorescent particle have similar energies \
d)The emission wavelength of a fluorescent particle cannot be determined
Homework Answers
Answer---- B
---> the excitation wavelength of a fluorescent particle is higher in energy than the emission wavelength.
Because emitted fluorescent light has higher wavelength and lower energy than the absorbed light, this is known as Stokes shift.

Rhodamine G is a popular fluorescent tag and it absorbs light at 475 nm. A series of fluorescence emission experiments were performed to examine the emission characteristics of rhodamine and one data point is given below. What is the most likely reason the emission intensity zero? Experiment λ excitation (nm) λ emission (nm) [Rhodamine] / mg/mL Emission Intensity (Unitless) 1 475 425 0.01 0.0 a. The intensity is being measured at a shorter wavelength than excitation so no emission would...

In comparing fluorescence spectroscopy to UV‑Vis absorption spectroscopy, which of the statements is true? Fluorescence measurements do not suffer deviations from linearity like absorbance measurements do. Fluorescence measurements are more precise and less noisy because only the intensity of the emitted light is measured. Fluorescence instruments are less expensive than absorption measurements. Fluorescence measurements have better detection limits because at low concentrations a low intensity emission signal is being measured against a low intensity background signal.
