Analytical Chemistry/Laser Spectrometry/Computer Simulations/S/N Analysis

Research in our group is directed toward the quantitative analysis of a variety of instrumental techniques of modern chemical analysis, particularly spectrometric techniques. Among the techniques currently employed or studied are laser-excited photoacoustic spectrometry, laser-excited multiphoton photoionization in condensed phase solutions, circular dichroism, optical polarimetry, UV/visible spectrophotometry and atomic absorption spectrometry. A major goal is the determination of optimum experimental realizations for, e.g., optical polarimetry. Toward this end, we perform detailed theoretical analyses of relevant signals and noises of the techniques under study. In conjunction with the analytic work, we perform quantitative behavioral modeling via microcomputer-based simulations that provide unparalleled verisimilitude with actual experiments. The simulation models we have developed are useful for verification of existing experimental results, from our group and the literature, and for prediction of the outcome of physical experiments that are, as yet, unperformed or even unperformable. A long-term goal of our research is the development of a comprehensive mathematical understanding of the analytic behavior of various noises, both white and nonwhite, in time-variant spectrometric systems. At present, most modern spectrometric techniques cannot be analyzed rigorously (hence cannot be rigorously optimized) because their associated noise analyses are all but intractable analytically. With the aid of our simulation models, we are able to determine how such systems behave and use this understanding to refine our analytic models.
