The analysis of mixtures is a problem commonly faced in analytical chemistry. In this work, pulsed-Γeld gradient NMR (PFG-NMR) experiments were used to analyze mixtures of polymer additives and simple polymer solutions. PFG-NMR experiments were also utilized to determine di β usion coefficients of th
## Abstract The current theoretical treatment of diffusion of gases in glassy polymers is based on the βdual sorptionβ model, but also includes certain other important assumptions, at least some of which cannot be fully justified __a priori__. They require experimental validation, which, however, i
Laser-field correlation effects on the Autler-Townes spectroscopy of the D 'H,(u ~2, I' =2)-E,F'Z: (u=6, J= 1) transition in Hz are examined theoretically using the phase-diffusion model for the laser-field fluctuations. Increase in effective laser bandwidth due to correlation effects in the two-ph
