Spin relaxation in NMR is known to provide information about the dynamics of molecular entities and possibly about molecular geometry or electron distribution. Generally, dynamical information is obtained if the tensor of the relevant relaxation mechanism is known from independent determinations. Conversely...

Distribution of relaxation times from quasi-elastic light-scattering experiments: high molecular weight polystyrene in cyclopentane at .theta. conditions Time correlation functions have been measured over extended spans of delay time for the θ system polystyrene (M = 15 × 106) in cyclopentane as a...
Because relaxation can be described by an equation with delay, each relaxation cycle that follows is different from the previous ones, in general. Some properties of the mathematical model under consideration are established. In particular, conditions are given, under which the long-term behaviour ...
Least-square fits of the delay-dependent yields are provided in Supplementary Figs. 9–11. The nature of the previously unreported broad, short-lived feature with BE values in the range ~1.5–7 eV is investigated further using high-level electronic structure calculations and non-adiabatic ...
The time during which they are ascending the energy ladder produces a delay time in the onset of unimolecular reaction: the incubation time. As the population distribution approaches steady state, the rate of unimolecular decay becomes an exponential function characterized by the steady-state ...
NMR relaxation of water 1 H confined in restricted geometries, whatever is the nature of the system (porous media saturated by water as well as biological tissues), exhibits common characteristics. Artificial microporous media saturated by water have been chosen as model systems to study the longitu...
The effect of the choice of the τ sequence in the inversion-recovery experiment is examined. The uncertainty in the value of T1 can be related to a function F of T1, the pulse interval delay, and the τi's. Minimization of the function for a range of T1's yields optimized sequences...
