Energy of Photochemical Reaction terms of Wavelength

Go Energy in Photochemical Reaction = ([Avaga-no]*[hP]*[c])/Wavelength

Wavelength given Energy of Reaction

Go Wavelength = ([Avaga-no]*[hP]*[c])/Energy in Photochemical Reaction

Number of Quanta absorbed in 1 second using Quantum Efficiency of Reactant

Go Number of Quanta Absorbed = Reactant Molecules Consumed per Second/Quantum efficiency for reactants

Number of Molecules of Reactant consumed in 1 second

Go Reactant Molecules Consumed per Second = Quantum efficiency for reactants*Number of Quanta Absorbed

Quantum Efficiency for Disappearance of Reactant

Go Quantum efficiency for reactants = Reactant Molecules Consumed per Second/Number of Quanta Absorbed

Number of Quanta absorbed in 1 second using Quantum Efficiency of Products

Go Number of Quanta Absorbed = Product Molecules Formed per Second/Quantum Efficiency for Products

Number of Molecules of Product formed in 1 second

Go Product Molecules Formed per Second = Quantum Efficiency for Products*Number of Quanta Absorbed

Quantum Efficiency for Formation of Product

Go Quantum Efficiency for Products = Product Molecules Formed per Second/Number of Quanta Absorbed

Frequency given Energy of Reaction

Go Frequency = Energy in Photochemical Reaction/[Avaga-no]*[hP]

Energy of Photochemical Reaction

Go Energy in Photochemical Reaction = [Avaga-no]*[hP]*Frequency

Intensity of Transmitted Light

Go Intensity of Transmitted Light = Intensity of incident light-Intensity of Light Absorbed

Intensity of Incident Light

Go Intensity of incident light = Intensity of Light Absorbed+Intensity of Transmitted Light

Intensity of Light Absorbed

Go Intensity of Light Absorbed = Intensity of incident light-Intensity of Transmitted Light

Intensity in J per second given Intensity terms of Photons

Go Intensity in J per second = Intensity in number of photons*Energy per Quantum

Intensity terms of Number of Photons absorbed in 1 second

Go Intensity in number of photons = Intensity in J per second/Energy per Quantum

Energy per Quantum given Intensity

Go Energy per Quantum = Intensity in J per second/Intensity in number of photons

Energy per Quantum of Radiation terms of Wavelength

Go Energy per Quantum = ([hP]*[c])/Wavelength

Energy per Quantum of Radiation Absorbed

Go Energy per Quantum = [hP]*Frequency

Quantum Efficiency for Formation of Product Formula

Quantum Efficiency for Products = Product Molecules Formed per Second/Number of Quanta Absorbed
Φ_p = dN_Pdt/I_quanta

What is Stark-Einstein law of photochemical equivalence?

Stark-Einstein law of photochemical equivalence can be stated as follows:
Each molecule taking part in a photochemical reaction absorbs one quantum of radiation
which causes the reaction. This law is applicable to the primary act of excitation of a molecule by light absorption. This law helps in calculating the quantum efficiency which is a measure of the efficiency of the use of light in a photochemical reaction.

What is Grotthuss-Draper Law?

According to this law, only the light that is absorbed by a molecule can produce a
photochemical change in it. This means that it is not sufficient to pass light through a
substance to bring about a chemical reaction; but the light must be absorbed by it.
Stark-Einstein law of photochemical equivalence provides a quantum mechanical form to
Grotthuss-Draper law.
