Atomic Line widths

        -    Uncertainty effect

        -    Doppler Broadening

        -    Pressure Broadening

Temperature and the Excited State
N_j/N_o = P_j/P_o exp (E_j/kT)

ATOMIC SPECTROSCOPY
Flame and Electrothermal
General Steps

Nebulization v-groove nebulizer (fine mist)
Desolvation initial T = cool part of the flame - Molecular aerosol mist
Volatilization single gaseous molecules excitation via molecular hv
Dissociation ATOMS EXCITATION via atomic hv
Ionization Ions ionic hv excitation
