Dear

**GrignardGirl**,

Who is “

**Lineburke**”?, - never heard of him/it, and it seems nobody (Google, Yahoo!, MSN, Alta Vista, etc.) else too!

Abs/min indicates a “

**Single Wavelength measurement**” (

**SWM**) for a Reaction, what seems to be not very wisely!

**But let’s do the little “brain acrobatics” anyway:**“

**Abs/min**” or more correct

**ΔAbs/Δt**, like

**dAbs/dt** is a “

**Reaction Rate**”, and if you use the “

**Special Beer-Lambert Law**” (for only a

**SWM** it’s enough) you have to write:

**ΔAbs/Δt ==> ΔA**_{λ}/Δt = Δ(ε_{λ} * c * d)/Δt

On the other side and from the definition of

**ε**_{λ}:

If you set for your case for

**A**_{λ} = 2500 AU into the “

**Special Beer-Lambert Law**”:

**A**_{λ} = ε_{λ} * c * d you will result in:

**2500 AU = 2500 L mole**^{-1} cm^{-1} * c * d

**Or with simple words:** **ε**_{λ} is “

**only**” the

**theoretical Absorbance** (value) for a Solution with Concentration = 1.00 Mole/L measured in a 1.00cm Cuvette with the given

**ε**_{λ}.

**And the final calculation:****2500 AU/min = 1.00 mole/min ===> 0.429AU/min = mole/min.**(I’m still searching for its real sense.)

Could this be of help to you?

Good Luck!
