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.
