Laser Spectroscopy Helps Measure Variations in Energy Transition within Cadmium Atoms

Atoms absorb and emit light of various wavelengths. Physicists have long known that there are some tiny changes, or shifts, in the light that gets absorbed or emitted, due to the properties of the atomic nucleus.

New Laser Technique for Resolving Orbits of Multiple Molecular Orbitals

A scientist in a crisp, white lab coat and protective eye goggles sits behind a safety shield, controller in hand. In front of him is a powerful titanium-sapphire laser, aimed at a crystal lens. His thumb gently squeezes the trigger on the controller. There is an imperceivable wisp of gas that is escaping from a nozzle and crossing the laser’s path. Before he can even blink his eye the laser is capable of firing more than a trillion times. On the screen a line of alternating pairs of glowing, amorphous spots appear. For the first time ever, someone has been able to peer down into the molecular level to observe simultaneously in two dimensions.

Alice Far-Ultraviolet Spectrograph Reveals Electrons as Cause of Water Molecules Breakup on Comet Surface

A close-up of Comet 67P/Churyumov-Gerasimenko by NASA's ultraviolet instrument surprised scientists by revealing that electrons close to the comet's surface -- not photons from the Sun as had been believed -- cause the rapid breakup of water and carbon dioxide molecules spewing from the surface.

McPherson Introduces Extended Lifetime Deep and Vacuum Ultraviolet Wavelength Spectral Test Systems

McPherson now offers extended lifetime deep and vacuum ultraviolet (VUV) wavelength spectral test systems. The VUV instruments are ideal for analyzing doped crystalline materials, deep UV optics, and coatings. They directly measure absolute transmission and variable angle reflectance. A gas cell attachment is used for high sensitivity absorption.

Subaru Telescope Helps Conduct Spectroscopic Observations on Solar-Type Superflare Stars

A team of astronomers has used the High Dispersion Spectrograph on the Subaru Telescope to conduct spectroscopic observations of Sun-like "superflare" stars first observed and cataloged by the Kepler Space Telescope. The investigations focused on the detailed properties of these stars and confirmed that Sun-like stars with large starspots can experience superflares.

New Photon Correlation Spectroscopy-Based Method for Directly Measuring Sound Pressure

Accurate measurements of airborne sound are needed for a range of regulatory, health and safety, and commercial applications, from monitoring environmental noise to testing the performance of acoustic devices. To ensure reliable measurements of sound pressure, microphones must be regularly calibrated by measuring their sensitivity over a certain frequency range.
