Fluorescence Rate Constant Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rate Constant of Fluoroscence = Rate of Fluoroscence/Singlet State Concentration
K_f = R_f/[M_S1]
This formula uses 3 Variables

Variables Used

Rate Constant of Fluoroscence - (Measured in Hertz) - Rate Constant of Fluoroscence is the rate at which spontaneous emission occurs.
Rate of Fluoroscence - (Measured in Mole per Cubic Meter Second) - Rate of Fluoroscence is the rate at which spontaneous emission occurs.
Singlet State Concentration - (Measured in Mole per Cubic Meter) - Singlet State Concentration is the number of molecules present in the singlet excited state.

STEP 1: Convert Input(s) to Base Unit

Rate of Fluoroscence: 15 Mole per Liter Second --> 15000 Mole per Cubic Meter Second (Check conversion here)
Singlet State Concentration: 2E-05 Mole per Liter --> 0.02 Mole per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_f = R_f/[M_S1] --> 15000/0.02

Evaluating ... ...

K_f = 750000

STEP 3: Convert Result to Output's Unit

750000 Hertz -->750000 Revolution per Second (Check conversion here)

FINAL ANSWER

750000 Revolution per Second <-- Rate Constant of Fluoroscence

(Calculation completed in 00.004 seconds)

What is Fluorescence?

Fluorescence, emission of electromagnetic radiation, usually visible light, caused by excitation of atoms in a material, which then reemit almost immediately (within about 10−8 seconds).

What is meant by fluorescence quenching?

Fluorescence quenching refers to any process that decreases the fluorescence intensity of a sample. A variety of molecular interactions can result in quenching. These include excited-state reactions, molecular rearrangements, energy transfer, ground-state complex formation, and colli-sional quenching.

How to Calculate Fluorescence Rate Constant?

Fluorescence Rate Constant calculator uses Rate Constant of Fluoroscence = Rate of Fluoroscence/Singlet State Concentration to calculate the Rate Constant of Fluoroscence, Fluorescence Rate Constant formula is defined as the rate constant of the rate equation for at which spontaneous emission occurs. It can emit a photon and in the process get converted back to the ground state. This is fluorescence and the fluorescence decay process is a first-order rate process with a rate constant denoted by kf. Rate Constant of Fluoroscence is denoted by K_f symbol.

How to calculate Fluorescence Rate Constant using this online calculator? To use this online calculator for Fluorescence Rate Constant, enter Rate of Fluoroscence (R_f) & Singlet State Concentration ([M_S1]) and hit the calculate button. Here is how the Fluorescence Rate Constant calculation can be explained with given input values -> 750 = 15/0.02.
