Computational methods Gaussian least-squares method

Figure 19.10 shows the CH resonance lines of the crystalline components of PVA fibers spun from the 10 wt% DMSO solution, which were selectively measured by the CPTl pulse sequence. This figure also shows the results of the lineshape analysis by the computer-aided least-squares method. In these fibers, it is necessary to introduce two Gaussians, lines lilt, and for line... 

The Role of Computers in Activation Analysis.— For many years spectral data accumulated by m.c.a. have been analysed by digital computers. Many complex schemes of spectrum analysis have been developed involving least-squares methods, iterative Gaussian fits to peaks, correlation of the subject spectrum with ideal or measured spectrum shapes, convolution methods, and many combinations and variations of these schemes. Quittner...
