stokes line

......................

Answer 2

The correct answer is (c) resonance line.

Lines that begin in the ground state atom are most frequently of interest in atomic absorption spectroscopy; these are called 'resonance lines'.

• Transitions start with one energized state then onto the next yield non-resonance lines.
• A spectral line brought about by an electron bouncing between the ground state and the main energy level in an atom or ion.
• It is the longest-wavelength line created by a leap to or from the ground state.
• Since most of the electrons are in the ground state in numerous astrophysical conditions, and because the energy expected to arrive at the principal level is the most un-required for any transition, resonance lines are the most grounded lines in the spectrum for some random atom or ion.
• Atomic oxygen ingests first at its resonance multiplet, which in spectroscopy is the permitted transition between the ground state and the energized condition of most reduced energy.
• The resonance line or multiplet is normally the most grounded in emission and absorption spectra.
