PHYSEEKS[CHEMYSTERY]

"Information is a dainty branches of data breaches."

Presume you are a researcher, asked to propose the report on a specific target. While conducting the search, you will get as relevant info as 'Modern/Instrumental Chemistry'; in some occasions you'll come with useless info and in another scenario, it will be a combo of two as like 'Classical/Wet Chemistry'. 'The Tool' constructs your powerful hero of data by piecing the admissible together and cleaning the garbage. Since information gathering process is the ultimate goal for any research work, to gear up choose a perfect tool for it.

TASK 1: If the task is to know about a strange person-A, the information is obtained through a person-B who is familiar with that person-A. Here person-B, the tool for you. 

TASK 2: Similarly, Spectroscopy is an instrumental technique used to study the analyte. The information about the substance under analysis is obtained through Electromagnetic radiation. Here EMR, the tool  for you. If you study the analyte with classical method, Chemical Reaction is the tool.

Spectroscopy, the branch of chemistry deals with the identification of specific molecule via the interaction between Electromagnetic radiation and matter. To put it in another way, it is the intersection zone of Physics and Chemistry means Physics is in search of puzzle structure of a molecule which is entitled as 'PHYSEEKS[CHEMYSTERY]', 

Description: SEEKS[]= in search of 

             MYSTERY= puzzle.

A query hinders our mind: Why should they(Electromagnetic radiation and Matter) interact? To respond this we can approach 'Guess and Check' strategy. 

STEP 1-GUESS: Now just roll your eyes @ TASK 1, what do you see there? It said person-B was our tool because person-B is the closest mate of person-A and vise versa, right? In parallel to this, for sure there is a good relationship between EMR and matter.

STEP 2-CHECK: To verify the predicted relation, we need a chemist and a physicist.

CHEMIST:   Hey Physicist! What is electromagnetic radiation?

PHYSICIST: EMR is a parcel of discrete energy called photons created when a charged particle is accelerated by electric field, causing it to move. This movement produces oscillating electric and magnetic field which are perpendicular to each other and to the direction of the wave. 

           EM radiation spans an enormous range of frequencies and wavelength called EM spectrum, a pack of very short gamma ray to very long radiowave.

SELF PROPAGATING WAVES

CHEMIST:   Got it.

PHYSICIST: I'm pretty confused with matter. Please spell out for me.

CHEMIST:   Most of the matter in the universe is a compound. A compound is a molecule. A molecule is a combination of atoms. An atom holds subatomic particles: electrons, protons and neutrons, of these electrons and protons carry a net electric charge that is quantized.

PHYSICIST: You mean a charged particle? Okay, these quantized charged particles does not normally emit EMR, but does so when placed under electric field that can be an electromagnetic radiation too. 

CHEMIST:   I feel we are nearing each other.

PHYSICIST: Yeah, I do feel the same.

CHEMIST:   Molecules under EMR, absorb certain wavelengths i.e., the energy of absorbed radiation is a precise value which causes excitation of a molecule from one energy state to higher state because these energy levels are also quantized meaning each one possess a discrete energy value as like non-adjustable ceiling fan.

           Consequently, on measuring the wavelength of the EMR absorbed by a molecule, it is possible for us to gain information about various energy levels which can be further correlated with molecular structure.

In a nutshell, 'Spectroscopy' touch on "Diamond cuts Diamond".
