Optimum repetition rates for dual-comb spectroscopy
Abstract:
The determination of the properties (i.e. line center, width, and amplitude) of a spectral line is simulated using a Monte Carlo method. For dual-comb spectroscopy, ideal repetition rates emerge for both the signal and LO combs that do not correspond to the repetition rates that possess the highest signal-to-noise ratio. The determination is even more accurate when the repetition rates have an arbitrary near-harmonic ratio. The simulation results are generalized to allow for the comparison of any two spectroscopic systems (i.e. not just comb-based systems) by performing the simulations as a function of the spectral point spacing and signal-to-noise ratio of the acquired data.

Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
Concentration and Rate Law
For example, in a generic reaction aA + bB ⟶ products, where a and b are stoichiometric coefficients, the rate law can be written as:
