Spectroscopy Magazine Commemorates the 54th Anniversary of the First Moon Walk
July 19, 2023
On July 20th, 1969, American astronauts Neil Armstrong and Buzz Aldrin made history by becoming the first humans to land on the moon. Today, 54 years later, Spectroscopy magazine highlights how spectroscopy is playing a role in advancing space exploration.
Mars Rover Uses Spectroscopy to Detect Diverse Organic-Mineral Associations in Jezero Crater
July 19, 2023
A Nature study reports the discovery of diverse organic-mineral associations in the Máaz and Séítah formations within Jezero crater on Mars, as observed by the Perseverance rover's SHERLOC instrument. The Raman and fluorescence findings indicate the presence of aromatic organic molecules within Martian soils.
Decimal Versus Binary Representation of Numbers in Computers
October 01, 2022
The past decision to use binary representation in computer architectures affects the results of chemometric-based outputs, especially if different data values are used.
A Survey of Basic Instrument Components Used in Spectroscopy, Part 3: Atomic Spectroscopy
September 01, 2022
In this third part of this four-part series on spectroscopy instrument components, we take a closer look at components used in atomic spectroscopy instrumentation—from beryllium and Kapton windows used in X-ray analysis to sampler and skimmer cones and plasma torches for ICP systems.
The 2022 Emerging Leader in Molecular Spectroscopy Award
September 01, 2022
Lu Wei of the California Institute of Technology, the 2022 winner of the Emerging Leader in Molecular Spectroscopy Award, is applying stimulated Raman scattering (SRS) microscopy for bioanalysis, spectroscopy-informed design of vibrational imaging probes, and sample-engineering strategies.
