Spectroscopy Definitions

Question 1

Spectroscopy

Answer 1

Absorption, emission or scattering of electromagnetic radiation

Question 2

Emission Spectrum

Answer 2

Light emitted by an element
Light passed through prism to separate energies
Unique for each element

Question 3

Bohr model and spectral lines

Answer 3

4 visible spectral lines of H correspond to transition of e- from higher energy levels to n=2

Question 4

Lyman Series

Answer 4

e- from higher energy level to n=1
Ultraviolet

Question 5

Baimer Series

Answer 5

e- from higher energy level to n=2
visible + ultraviolet

Question 6

Paschen Series

Answer 6

e- from higher energy level to n=3
infrared

Question 7

Absorption spectroscopy

Answer 7

light pass through a gas which absorbs some wavelengths of light, leaving dark lines where wavelength absorbed

Question 8

Atomic Absorption Spectroscopy (AAS)

Answer 8

Quantitive technique absorbs certain frequencies of light
Can be related to concentration of metal by a calibration curve
