Chris Anthony coauthored the 1964 study of a bacterial <methanol dehydrogenase> with <L. J. Zatman>. His own research account explicitly connects his name with the initial-only Anthony–Zatman publications.<Chris Anthony research account and personal homepage>[Research career and linked publication history: 1964 methanol-oxidizing enzyme paper]{ref}
The experiment measured an optical response associated with <electron transfer>, using a <dye-linked enzyme assay>. The paper describes a Unicam SP.500 <spectrophotometer> and $10\,\mathrm{mm}$ <cuvettes>. Establishing the <reaction product> required separate chemical analysis rather than the optical signal alone.<The microbial oxidation of methanol. 2. The methanol-oxidizing enzyme of Pseudomonas sp. M 27 by C. Anthony and L. J. Zatman>[p.614, Materials and Methods; p.620, product analysis]{ref}
For an original illustration of the optical measurement, assume the <Beer-Lambert law>
$$
A=\varepsilon\ell c
$$
with <absorbance> $A=0.20$, liquid path $\ell=1.0\,\mathrm{cm}$ and a hypothetical molar coefficient $\varepsilon=10^4\,\mathrm{L\,mol^{-1}\,cm^{-1}}$. Then
$$
c=\frac{0.20}{10^4\times1.0}=2.0\times10^{-5}\,\mathrm{mol\,L^{-1}}.
$$
A decrease of $0.05$ absorbance units would correspond to a $5\times10^{-6}\,\mathrm{mol\,L^{-1}}$ decrease of the absorbing species under those assumptions. It does not by itself give the amount of <methanol> consumed: the chemical identity of the absorber and the coupling <stoichiometry> must also be known. The coefficient and measurements are invented for this example.
