Chapter 19, Problem 19.10P

Interpretation Introduction

Interpretation:

Values of $\left[\text{X}\right]$ and $\left[\text{Y}\right]$ have to be verified.

Concept Introduction:

Molar absorptivity is a coefficient that appears in Beers’ law. It measures the extent of light absorbed at a certain wavelength. Molar absorptivity is denoted by the symbol $\epsilon$. SI unit for Molar absorptivity is ${\text{M}}^{-1}{\text{cm}}^{-1}$.

Relation between path length and dimension is as follows:

  $D=b\left(\text{ε}{\text{'}}_{\text{X}}\text{ε}{"}_{\text{Y}}-\text{ε}{\text{'}}_{\text{Y}}\text{ε}{"}_{\text{X}}\right)$

Here,

$\epsilon$ denotes molar absorptivity in ${\text{M}}^{-1}{\text{cm}}^{-1}$.

$b$ denotes path length in centimeters.

$D$ denotes dimension.
