used in analytical chemistry, and provide a wide range of quantitative and qualitative information

spectrometric technique

a form of energy that is transmitted through space at enormous velocities

electromagnetic radiation

electromagnetic radiation can be described as ____ with properties of wavelength, frequency, velocity and amplitude

wave

electromagnetic radiation can be treated as discrete packets of energy or particles called _____

photons or quanta

The energy associated with electromagnetic radiation covers a wide range of magnitude as do the corresponding frequencies and wavelengths

electromagnetic spectrum

the number of oscillations that occur in one second

frequency

the distance between identical points

wavelength

transmitted via electromagnetic waves that are characterized by their frequency and wavelength

energy

is a vector quantity that provides a measure of the electric or magnetic field strength at a maximum in the wave

amplitude

is the time in seconds for successive maxima or minima to pass a point in space.

period

unit of frequency

hertz

The velocity of the wave front through a medium depends on both the medium and the frequency

velocity

is another way to describe electromagnetic radiation. It is most often used to describe radiation in the infrared region

wave number

a particle of epectromagnetic radiation HAVING ZERO MASS and ENERGY of hv

photon

the visible region of the spectrum from about 400nm to almost 800nm

visible region

are spectroscopic methods based on ultraviolet, visible, and infrared radiation

optical methods

literally multicolored light, is light of many wavelengths

polychromatic light

defined as radiation from the instrument that is outside the nominal wavelength band chosen for the determination

stray light

the visible region of spectrum

400nm to 800nm

stray radiation is commonly called ____

stray light

highest energy, highest frequency, shortest wavelength

gamma rays

used to study atomic structures and medical imaging

x rays

it lies between visible light and x-rays and also used in UV visible spectroscopy to study organic transitions in molecules

ultraviolet

the light we can see, ranging from violet to red

visible light

Used in IR spectroscopy to study molecular vibrations and identify functional groups in organic molecules

infrared

Lower energy, longer wavelengths.

microwaves

Lowest energy, lowest frequency, longest wavelength.

radio waves

usually refers to methods in which the stimulus is heat or electrical energy

emission spectroscopy

refers to excitation of the analyte by a chemical reaction

chemiluminescence spectroscopy

we measure the amount of light absorbed as a function of wavelength

absorption spectroscopy

the emission of photons is measured

photoluminescence spectroscopy

what are the most important forms of photoluminescence for analytical purposes

fluorescence and phosphorescence

tells us quantitatively how the amount of attenuation depends on the concentration of the absorbing molecules and the path length over which absorption occurs

beers law

This states that the concentration of a substance if directly proportional to the amount of light absorbed or inversely proportional to the logarithm of transmitted light

beers law
