Singlet State Concentration Solution

Follow our step by step solution on how to calculate Singlet State Concentration?

FIRST Step Consider the formula

[M Ss1] = \frac{I a}{K f + K NR + K ISC + K IC}

Next Step Substitute values of Variables

∴

[M Ss1] = \frac{250W/m²}{750rev/s + 35rev/s + 64000rev/s + 45.5rev/s}

Next Step Convert Units

∴

[M Ss1] = \frac{250W/m²}{750Hz + 35Hz + 64000Hz + 45.5Hz}

Next Step Prepare to Evaluate

∴

[M Ss1] = \frac{250}{750 + 35 + 64000 + 45.5}

Next Step Evaluate

∴

[M Ss1] = 0.00385620965440649mol/m³

Next Step Convert to Output's Unit

∴

[M Ss1] = 3.85620965440649E-06mol/L

LAST Step Rounding Answer

∴

[M Ss1] = 3.9E-6mol/L

How to Evaluate Singlet State Concentration?

Singlet State Concentration evaluator uses Concentration of Singlet State = Absorption Intensity/(Rate Constant of Fluoroscence+Rate Constant of Non Radiative Reaction+Rate Constant of Intersystem Crossing+Rate Constant of Internal Conversion) to evaluate the Concentration of Singlet State, The Singlet State Concentration formula is defined as is the number of molecules present in the singlet excited state. The concentration of a substance is the quantity of solute present in a given quantity of solution. Concentrations are usually expressed in terms of molarity, defined as the number of moles of solute in 1 L of solution. Concentration of Singlet State is denoted by [M_Ss1] symbol.

How to evaluate Singlet State Concentration using this online evaluator? To use this online evaluator for Singlet State Concentration, enter Absorption Intensity (I_a), Rate Constant of Fluoroscence (K_f), Rate Constant of Non Radiative Reaction (K_NR), Rate Constant of Intersystem Crossing (K_ISC) & Rate Constant of Internal Conversion (K_IC) and hit the calculate button.

FAQs on Singlet State Concentration

What is the formula to find Singlet State Concentration?

The formula of Singlet State Concentration is expressed as Concentration of Singlet State = Absorption Intensity/(Rate Constant of Fluoroscence+Rate Constant of Non Radiative Reaction+Rate Constant of Intersystem Crossing+Rate Constant of Internal Conversion). Here is an example- 3.9E-9 = 250/(750+35+64000+45.5).

How to calculate Singlet State Concentration?

With Absorption Intensity (I_a), Rate Constant of Fluoroscence (K_f), Rate Constant of Non Radiative Reaction (K_NR), Rate Constant of Intersystem Crossing (K_ISC) & Rate Constant of Internal Conversion (K_IC) we can find Singlet State Concentration using the formula - Concentration of Singlet State = Absorption Intensity/(Rate Constant of Fluoroscence+Rate Constant of Non Radiative Reaction+Rate Constant of Intersystem Crossing+Rate Constant of Internal Conversion).

Can the Singlet State Concentration be negative?

Yes, the Singlet State Concentration, measured in Molar Concentration can be negative.

Which unit is used to measure Singlet State Concentration?

Singlet State Concentration is usually measured using the Mole per Liter[mol/L] for Molar Concentration. Mole per Cubic Meter[mol/L], Mole per Cubic Millimeter[mol/L], Kilomole per Cubic Meter[mol/L] are the few other units in which Singlet State Concentration can be measured.
