The reason for this is that the window and non-window radiation have already been conditioned by the Beer-Lambert Law and the law cannot validly be re-applied to its own products.
32.
This is a deep conceptual point that distinguishes the kinetic description of window and non-window radiation from the kinetic description of the kind of radiation that is covered by the Beer-Lambert Law.

The strength of the gas absorption will depend, as given by the Beer-Lambert law, both on the gas concentration and the path-length that the light has travelled through the gas.
34.
The measurement adds reagents including a molybdate compound and a reducing agent to produce a blue silico-molybdate complex color which is detected optically and is related to concentration according to the Beer-Lambert law.
35.
According to the Beer-Lambert law, the amount of light absorbed by the gas is proportional to amount of the gas present in the light s path; therefore this technique is a direct measurement of moisture.

Cuvettes are typically rectangular in shape, commonly with an internal width of 1 cm . ( This width becomes the path length, L, in the Beer-Lambert law . ) Test tubes can also be used as cuvettes in some instruments.

:An important article dealing with this is the Beer Lambert law, which describes the relationship between the intensity of a color in a solution to the properties of that solution .-- contribs 00 : 34, 9 January 2009 ( UTC)

I've used spectrometry to obtain absorbencies, and I've been given an ? 280 ( constant at 280nm ) value to use in the simplified Beer-Lambert law ( concentration = absorbency / ? 280 ), so I can work out concentration like that.
39.
Hence, assuming that the ideal inter-layer distance of two graphene sheets is d _ { graphite } = 0.335 nm, as in graphite, one can calculate the absorption coefficient of graphene according to the Bouguer-Lambert law to 301655 cm ^ {-1 }.

Whose solution is known as Beer-Lambert law and has the form I = I _ { 0 } e ^ {-x / \ ell }, where is the distance traveled by the beam through the target, and is the beam intensity before it entered the target; is called the mean free path because it equals the mean distance traveled by a beam particle before being stopped.
