List of top Pharmaceutical Analysis Questions on Principles of spectroscopy

In atomic absorption spectroscopy, back ground correction performed using a single hollow cathode lamp pulsed first with a low current and then with a high current is called:

Identify what is not a continuum source of radiation for use in absorption and fluorescentspectrophotometers?

Predict the wavelength of absorption band in the UV spectrum of the below shown structure:

Given below are two statements, one is labelled as Assertion and the other is labelled as Reason
Assertion (A): The disadvantage of atomic absorption spectroscopy is the need for each element to be analysed. 
Reason (R): As atomic absorption spectrophotometer uses different halocathode lamp for each element, it is very specific for an individual element under test. 
In light of the above statements, choose the correct answer from the options given below:
