Triplet State Quantum yield Solution

Follow our step by step solution on how to calculate Triplet State Quantum yield?

FIRST Step Consider the formula

φ triplet = \frac{K ISC \cdot [M S1]}{I a}

Next Step Substitute values of Variables

∴

φ triplet = \frac{64000rev/s \cdot 2E-5mol/L}{250W/m²}

Next Step Convert Units

∴

φ triplet = \frac{64000Hz \cdot 0.02mol/m³}{250W/m²}

Next Step Prepare to Evaluate

∴

φ triplet = \frac{64000 \cdot 0.02}{250}

LAST Step Evaluate

∴

φ triplet = 5.12
