We studied in the earlier posts that the Stark-Einstein law holds true only for the primary process of a photochemical reaction. However, we never studied
In the last post, we started talking about quantum yield. This quantity tells us how many molecules react by absorbing how many quanta of light.
A post on photons and rest mass.
In this post we are going to understand the exponential factor in Beer – Lambert’s law, by assigning imaginary values to different parameters in the
Xenon Lamp – This is a gas discharge lamp where electricity is passed through ionized gas (xenon) at high pressure , to produce light. Gas
In the previous post we studied the basic components of a spectrophotometer. Now let us learn each component in a little more detail. Light source
In the previous post we studied the following equation for Beer – Lambert’s law – We understood that if we decide the intensity of incident
You have encountered the above expression while studying Beer – Lambert’s law ,right? And did you wonder what this means? How do you arrive at
In the last few posts we have been discussing the Beer – Lambert’s law and various terms associated with it. In this post we are
Absorbance In the previous post, we introduced the term absorbance. The term absorbance quantifies the amount of light absorbed by a solution. We know from
Absorbance and Transmittance Absorbance(A) and transmittance(T) are two sides of a coin. Absorbance (A) is the amount of light absorbed and transmittance is the the
The Lambert’s Law We studied in the previous post, that according to Lambert’s law, absorbance (A) is directly proportional to the path length or thickness
