    Spectroscopy Spectroscopy is the study of energy levels in atoms or molecules, using absorbed or emitted electromagnetic radiation. There are many categories of spectroscopy eg. Atomic and infrared spectroscopy, which have numerous uses and are essential in the world of science. When investigating spectroscopy four parameters have to be considered; spectral range, spectral bandwidth, spectral sampling and signal-to-noise ratio, as they describe the capability of a spectrometer. In the world

    world began to study light and colors. In the beginning, not much was known about colors and what caused certain shades to appear. It wasn’t until 1859 when two German scientists created the foundation for the study of spectroscopy and colors (Historical Introduction to Spectroscopy). Robert Wilhelm Bunsen grew a fascination with light when he first observed that certain colors were emitted when chemicals were burned under his flame lamp invention, the Bunsen Burner (Scratch). Why did some chemicals

    In infrared (IR) spectroscopy, infrared light interacts with molecules of the substance. The collected data is used to determine the substance. Infrared light is a part of the electromagnetic spectrum and contains longer wavelengths than visible light. In this type of spectroscopy, an IR beam passes through the sample substance. Consequently, the covalent bonds absorbs the beam, thus this causes a change in the vibrations of the dipole moment in the substance. This spectroscopy is primarily used

    Asha Kurup April 3rd, 2014 IR Spectroscopy Assignment A. What is spectroscopy and how does it work? Spectroscopy is a term for analyzing spectra. The spectra may be visible light, infrared, ultraviolet, X-ray, and other types1. When a beam of light hits a triangular prism, it is separated into its components (ROYGBIV). Figure 1: Components of Light Spectroscopy is measured using a spectrophotometer. A beam of light is first pointed towards the spectrophotometer. The beam of light then strikes

    Vibrational spectroscopy is a term used to describe the analytical techniques Infrared and Raman spectroscopy. These two techniques are tools used to provide information about the molecular composition, structure and interactions with a sample. Both techniques are non-destructive, qualitative and rapid. They measure the vibrational energy levels that are affiliated with the chemical bonds in a sample. IR and Raman spectra are complementary to each other and provide scientists with images of vibrations

    Spectroscopy is the analogy between radiated energy, a source of matter and helps with the study of colours. Spectroscopy allows us to see how atoms emit and absorb electromagnetic radiation. Typically these measures are known to be a spectroscope. It allows us to measure how light is emitted, scattered or absorbed by a source of material. In addition the importance of spectroscopy is that it allows us to identify study and quantify a source of material. The different colour spectrum for light includes

    Raman spectroscopy is capable of depth profile, in-situ kinetic measurement and temperature calculation. Combining with SERS sensor, the weak Raman scattering could be dramatically enhanced, which is usually called Surface-enhance Raman spectroscopy (SERS). It will provide a powerful technique to observe very subtle bond variation information in ultra-thin film samples and interphases. This study attempts to understand the in-situ kinetic surface nano-structure, reaction and interfacial analysis

    • 3 Pages

    Introduction Spectroscopy is defined as the interaction between light and matter as it is a type of instrumentally aided study of the interaction between energy (certain part of electromagnetic spectrum) and the matter which is the sample intended to be analysed. Infrared is a part of electromagnetic spectrum which located between the visible light region and the microwave region. Hence, infrared spectroscopy is a type of spectroscopy technique that utilize the electromagnetic radiation in the infrared

    Objective: This paper is the summary of the infrared spectroscopic technique. Introduction: Spectroscopy basically involves the study of the interaction of radiated energy with matter. These different radiations could be used to study chemical and physical material properties of different atoms. Colors of light differ in wavelength and energies and when they interact with matter, the light is either scattered, reflected, transmitted, absorbed, reflected or fluorescence. The interaction makes vibrational

    In the determination of the structures of compounds and their identification, organic chemists commonly use infrared spectroscopy. It uses infrared radiation to explore the interaction of matter and energy. Infrared radiation is distinct to ultraviolet and visible light because it has particular effects on the molecule when absorbed. The principle behind infrared spectroscopy is the based on the vibrations of atoms in the molecule (Osibanjo, Curtis, & Lai, 2017). Vibrations occur when a molecule
