Description

Quantum beat spectroscopy is an experimental method that utilizes the interference between energetic transitions in atoms and molecules to detect energy level structures, dipole moments and resonances in complex molecules to a high degree of accuracy. Typically these processes require a high degree of time sensitivity however, in this work we show that specific, off-resonant, experimental parameters can be used to create these quantum beats at much lower frequencies while still maintaining significant signal amplitude. This may prove advantageous in improving the quality and ease of these measurements. An analytic calculation, involving a general three-level V system, is used to determine where these off-resonant parameters can be found and a numerical calculation is used to illustrate the decoherence-limited nature of these low-frequencies.
