With the availability of commercial field-cycling (FC) relaxometers together with progress of home-built instruments, NMR relaxometry has gained new impetus as a method of investigating the dynamics in polymer systems. The FC method provides the disp

(1)H nuclear magnetic resonance (NMR) field cycling relaxometry has been applied to study the dynamics of homologues of glycerol (propylene glycol, 2,3-butandiol, glycerol, threitol, xylitol, sorbitol) and non-alcohol liquids (o-terphenyl, tristyrene

We apply field cycling NMR to study segmental reorientation dynamics in melts of linear 1,4-polybutadiene (PB) in the entanglement regime (M ≥ Me). Dispersion data of the spin−lattice relaxation time T1(ω) are transformed to the susceptibility r

We have obtained depolarized (anisotropic) light scattering spectra of the glass forming material glycerol in a wide temperature (160 to 430 K) and frequency (0.4 GHz to 48 THz) range and compared them with light scattering and dielectric spectroscop

We report 2H NMR spin−lattice relaxation times T1 and spectra of two fragile molecular glass forming liquids, deuterated o-terphenyl-d14 (OTP) and toluene-d5, confined in a nanoporous SBA-15 type matrix with a pore diameter of 7.1-nm size. We compa

Photon correlation data of the molecular glass-forming materials 2-picoline, dimethylphthalate (DMP) and salol are compared with their dielectric loss spectra in the time-frequency range where the dielectric data reveal secondary relaxations. Slow se
