For the following characteristics of optical spectroscopy, determine if it applies to absorption spectroscopy or luminescence spectroscopy: small signal on small background small signal on large background requires use of two monochromators limited applicability to species that emit light requires use of one monochromator can be used to detect any atom or molecule

Solution

1. small signal on small background: luminescence

2. small signal on large background: absorption

3. requires use of two monochromators: luminescence

4. limited applicability to species thhat emit light: luminescence

5. requires use of one monochromator: absorption

6. can be used to detect any atom or molecule: absorption
