STEP 1: Convert Input(s) to Base Unit

Absorption Intensity: 250 Watt per Square Meter --> 250 Watt per Square Meter No Conversion Required
Rate Constant of Fluoroscence: 750 Revolution per Second --> 750 Hertz (Check conversion here)
Rate Constant of Non Radiative Reaction: 35 Revolution per Second --> 35 Hertz (Check conversion here)
Rate Constant of Intersystem Crossing: 64000 Revolution per Second --> 64000 Hertz (Check conversion here)
Rate Constant of Internal Conversion: 45.5 Revolution per Second --> 45.5 Hertz (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

[M_Ss1] = I_a/(K_f+K_NR+K_ISC+K_IC) --> 250/(750+35+64000+45.5)

Evaluating ... ...

[M_Ss1] = 0.00385620965440649

STEP 3: Convert Result to Output's Unit

0.00385620965440649 Mole per Cubic Meter -->3.85620965440649E-06 Mole per Liter (Check conversion here)

What is Absorbance ?

Absorbance is defined as "the logarithm of the ratio of incident to transmitted radiant power through a sample (excluding the effects on cell walls)". Alternatively, for samples which scatter light, absorbance may be defined as "the negative logarithm of one minus absorptance, as measured on a uniform sample".

What is Fluoroscence ?

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation.

How to Calculate Singlet State Concentration?
