An absorption measurement with a 1 cm path length yields a reading of 0.004 absorbance units with a noise of 0.001 absorbance units and a mean noise reading of 0 for 10 scans averaged together. Assuming the noise for a single scan does not change if the path length is increased to 6 cm and the number of scans is increase to 100, what is the signal to noise of the new measurement.
Electronic Transitions and Spectroscopy
The term “electronic” connotes electron, and the term “transition” implies transformation. In a molecule, the electrons move from a lower to a higher energy state due to excitation. The two energy states, the ground state and the excited state are the lowest and the highest energy states, respectively. An energy change is observed with this transition, which depicts the various data related to the molecule.
Photoelectron Spectroscopy
Photoelectron spectroscopy (PES) is a part of experimental chemistry. It is a technique used in laboratories that involves projecting intense beams of radiation on a sample element. In response, the element ejects electrons for which the relative energies are measured.
