Question

Increase the intensity of absorption in UV visible spectrum is called

Answer 1

Answer:

UV VIS spectroscopy....

Answer 2

Answer:

Hyperchromic shift

Concept:

• Spectroscopy: The study of the interaction of electromagnetic radiation with matter is called spectroscopy.

• Spectrum: The range of intensities or wavelength.
• Electromagnetic radiation: A radiation energy in the form of electric and magnetic wave transmitting in a space with certain velocity.
• Absorption: When electron gain some energy from the radiation and excite from ground state to the excited state is known as absorption.
• UV visible spectroscopy: It involves the measurement of absorption if light in the UV and visible region( 200 to 800 nm).

Explanation:

• Hyperchromic shift: In this shift the intensity of absorption increases due to the introduction of Auxochrome, which helps to absorb more radiations.

• Auxochrmes: A group attached to a chromophores helps to increase the absorption.

• Chromophores: A group which absorbs radiation and responsible for colors we can see.
