Observed Lifetime Given Quenching Time Solution

STEP 0: Pre-Calculation Summary

Formula Used

Observed Lifetime = ((Self Quenching Time*Quenching Time)+(Radiative Lifetime*Quenching Time)+(Self Quenching Time*Radiative Lifetime))/(Radiative Lifetime*Self Quenching Time*Quenching Time)
τ_obs = ((τ_s*τ_q)+(τ₀*τ_q)+(τ_s*τ₀))/(τ₀*τ_s*τ_q)
This formula uses 4 Variables

Variables Used

Observed Lifetime - (Measured in Femtosecond) - Observed Lifetime is the total lifetime for collision-induced predissociation and quenching rates for iodine via two-body collision kinetics.
Self Quenching Time - (Measured in Femtosecond) - Self Quenching Time refers to time for any process which decreases the fluorescent intensity of a given substance on its own.
Quenching Time - (Measured in Femtosecond) - Quenching Time is the quenching time due to collisions with the gas.
Radiative Lifetime - (Measured in Femtosecond) - Radiative Lifetime is the time for radiations in the absence of collisions.

STEP 1: Convert Input(s) to Base Unit

Self Quenching Time: 6 Femtosecond --> 6 Femtosecond No Conversion Required
Quenching Time: 8 Femtosecond --> 8 Femtosecond No Conversion Required
Radiative Lifetime: 4 Femtosecond --> 4 Femtosecond No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

τ_obs = ((τ_s*τ_q)+(τ₀*τ_q)+(τ_s*τ₀))/(τ₀*τ_s*τ_q) --> ((6*8)+(4*8)+(6*4))/(4*6*8)

Evaluating ... ...

τ_obs = 0.541666666666667

STEP 3: Convert Result to Output's Unit

5.41666666666667E-16 Second -->0.541666666666667 Femtosecond (Check conversion here)

FINAL ANSWER

0.541666666666667 ≈ 0.541667 Femtosecond <-- Observed Lifetime

What is femtochemistry?

Femtochemistry is the area of physical chemistry that studies chemical reactions on extremely short timescales (approximately 10 seconds or one femtosecond, hence the name) in order to study the very act of atoms within molecules (reactants) rearranging themselves to form new molecules (products).

How to Calculate Observed Lifetime Given Quenching Time?

Observed Lifetime Given Quenching Time calculator uses Observed Lifetime = ((Self Quenching Time*Quenching Time)+(Radiative Lifetime*Quenching Time)+(Self Quenching Time*Radiative Lifetime))/(Radiative Lifetime*Self Quenching Time*Quenching Time) to calculate the Observed Lifetime, The Observed Lifetime Given Quenching Time formula is defined as average time taken for a molecule after absorption to return to its ground state. It is measured with the help of quenching time. Observed Lifetime is denoted by τ_obs symbol.

How to calculate Observed Lifetime Given Quenching Time using this online calculator? To use this online calculator for Observed Lifetime Given Quenching Time, enter Self Quenching Time (τ_s), Quenching Time (τ_q) & Radiative Lifetime (τ₀) and hit the calculate button. Here is how the Observed Lifetime Given Quenching Time calculation can be explained with given input values -> 5.4E+14 = ((6E-15*8E-15)+(4E-15*8E-15)+(6E-15*4E-15))/(4E-15*6E-15*8E-15).

FAQ
