40 results found for spectroscopy

It seems likely that C60+ will act as a stable site for a wide variety of adducts and that these entities will contribute to the Diffuse Interstellar Bands.  John Maier's group in Basel is looking for species like C60(Fe)+.

The early (mid 1990s) work on the electronic spectroscopy was carried out by John Maier's group, trapping C60+ in a neon matrix in this apparatus.

John Maier's team at the University of Basel solved the riddle of C60+ in 2015.  In this brief view Colin Byfleet looks at the unique apparatus used in John's work.

The presentation the solution to this long-standing puzzle occurred at a most serendipitous moment.  John Maier, Professor of Physical Chemistry at the University of Basel reveals the momentous details.

John Maier, Professor of Physical Chemistry at the University of Basel, describes the journey from the prediction of C60+ in 1987, through tentative assignment of its electronic spectrum by Radioastronomy, measurement in a neon-matrix and finally, in....

I will discuss my random walk in science, from my graduate student on postdoctoral years testing the Weinberg-Salam-Glashow theory of electro-weak forces, and then to energy transfer in condensed matter systems, the spectroscopy of positronium, laser....

The spectrum of a frequency comb, commonly generated by a mode-locked femtosecond laser, consists of several hundred thousand precisely evenly spaced spectral lines. Such laser frequency combs have revolutionized the art of measuring the frequency of....

For the discovery of the physics phenomenon of nuclear magnetic resonance (NMR), Felix Bloch and Edward Purcell were awarded the Nobel Prize in Physics in 1952. NMR has then been used in a wide range of fundamental studies in physics, and in the 1960....

George Whitesides is the Woodford L. and Ann A. Flowers University Professor of Chemistry at Harvard University. Best-known for his work in NMR spectroscopy, organometallic chemistry, molecular self-assembly and nanotechnology, here he introduces sof....

It is hard to believe there was a time before batteries! Batteries and supercapacitors are at the heart of electric vehicles, portable devices (watches, laptops, mobile phones) and renewable resources like wind and solar, for energy storage. Bette....

Dr. Kroto describes his ABC system for spectroscopy, a systematic method that can be applied to vibrational, rotational, and electronic spectrocopies

The Optical Frequency Comb concept and technology exploded in 1999-2000 from the synthesis of advances in independent fields of Laser Stabilization, UltraFast Lasers, and NonLinear Optical Fibers. The Comb was developed first as a method for optical....

In 1952, Felix Bloch and Edward Purcell were awarded the Nobel Prize in Physics for the description of the phenomenon of nuclear magnetic resonance (NMR). Over the years, NMR has been used in a wide range of fundamental studies in physics, and in the....

In an evangelical spirit, three vignettes will be presented that have the character of molecular parables: stories with lessons that transcend the specific details.(1) How knowledge of the orientation of a methyl group with respect to a neighboring d....

As an introduction, some principles of nuclear spin physics applying to studies of integral membrane proteins (IMP) will be reviewed.  Applications of resulting nuclear magnetic resonance (NMR) techniques will then be illustrated with studies of G-p....

Some observers might think that fierce scientific competition borders on a rat race.  According to Wikipedia: "A rat race is an endless, self-defeating, or pointless pursuit.  It conjures up the image of the futile efforts of a lab rat trying to es....

The spectrum of a frequency comb, commonly generated by a mode-locked femtosecond laser consists of several hundred thousand precisely evenly spaced spectral lines.  Such laser frequency combs have revolutionized the art measuring the frequency of l....

The simple Balmer spectrum of atomic hydrogen has provided the Rosetta stone for deciphering the strange laws of quantum physics during the early 20th century.  Four decades ago, Doppler-free laser spectroscopy opened a new chapter in the exploratio....

Magnetic resonance imaging (MRI) is routinely used in hospitals to image internal structure and blood flow within the human body. Research has shown that it is possible to harness these techniques to study non-biological systems, with many applicatio....
