Abstract

The present dielectric and nuclear magnetic resonance (NMR) experiments show that viscous 2-methyl tetrahydrofuran (MTHF) exhibits a number of features typical for glass-forming liquids. These include the existence of a high-frequency contribution to the dielectric loss as well as indications for a secondary process which bears the signature of a Johari-Goldstein relaxation. The dielectric losses of MTHF were analyzed using an expression based on a generalized gamma function and yielded parameters that were similar to those of another small-molecule viscous liquid, meta-fluoroaniline.
