Techniques For Improving Parameter Estimation In Esr, Troy R. Broderick
Physics
This paper is to address the need for better estimates of the ESR spectral parameters of biological systems. In this paper I focus on models of spectral lineshapes and will be applying these techniques to more complicated lineshapes. Multifrequency ESR is a powerful technique for identifying and characterizing dynamic modes in natively unfolded biopolymers in general and loop regions in particular. I will introduce the reader to properties of ESR, formalisms and common techniques in the field. A common result for a simple ESR line is a Lorentzian distribution that is characterized by a mode and width. Information about the …
