Coherent-optical-control schemes exploit the coherence of laser pulses to change the phases of interfering dynamical pathways and manipulate dynamical processes. These active control methods are closely related to dynamical decoupling techniques, popularized in the field of quantum information. Inspired by nuclear magnetic resonance spectroscopy, dynamical decoupling methods apply sequences of ...
BIRD's eye view: Adding periodic BIRD J-refocusing (BIRD=bilinear rotation decoupling) to data acquisition in an HSQC experiment causes broadband homonuclear decoupling, giving a single signal for each proton chemical shift. This pure shift method improves both resolution and signal-to-noise ratio, without the need for special data processing.
Detecting a new area of contrast enhancement in or in the vicinity of a previously treated brain tumor always causes concern for both the patient and the physician. The question that immediately arises is whether this new lesion is recurrent tumor or a treatment effect. The differentiation of recurrent tumor or progressive tumor from radiation injury after radiation therapy is often a radiologi...
This article intends to give an overview of the capabilities of photoelectron spectroscopy !n determining the electronic structure of bulk solids, thin films, and surfaces. Particular :mphasis is placed on the use of synchrotron radiation as a tunable, polarized, and wellzollimated light source. Current trends in the field are higlilighted, and examples from the wthor's recent experience are gi...
Abstract Recommendations are given concerning the terminology of concepts and methods used in spectroscopy analytical chemistry, covering nuclear magnetic resonance spectroscopy, atomic vibrational spectroscopy.
