Electromagnetic radiation monochromatic

Monochromatic light Electromagnetic radiation of a single wavelength in the visible range. 

In LEIS, which is conceptually quite similar to PES, the sample is irradiated with a monochromatic electromagnetic radiation (e.g., a laser). Thus, it is possible to excite electrons from the sample to energy levels approaching or even surpassing the ionization barrier [94], The difference between LEIS and RIS is the mechanism... 

As with prisms, there are other devices that have been historically used for dispersing or filtering electromagnetic radiation. These include interference filters and absorption filters. Both of these are used for monochromatic instruments or experiments and find little use compared to more versatile instruments. The interested reader is referred to earlier versions of instrumental analysis texts.

For many reasons atomic spectroscopy continues to be one of the most rapidly developing branches of physics. This is primarily due to the creation of very stable and monochromatic lasers, allowing one to selectively excite various atomic states, to create very highly excited (Rydberg) atoms, and due to the occurrence of new possibilities, given by non-atmospheric astrophysics, which allow one to register the electromagnetic radiation... 

To illustrate this phenomenon, we return to the molecular hydrogen ion H2+. The ground vibrational state of the system is bound in the potential depicted in Figure 1.13. Suppose now that we expose the system to a monochromatic electromagnetic radiation with a frequency radiation field now couples between the ground electronic state and the excited electronic state of the system. The excited electronic state of the hydrogen molecular ion is a dissociative potential curve, which is well approximated by [48] ... 

Consider a group of molecules of dipole moment operator p that are shined by a monochromatic isotropic electromagnetic radiation.

Molecular weight Synonymous with molecular mass. Monochromatic radiation Ideally, electromagnetic radiation that consists of a single wavelength in practice, a very nan ow band of wavelengths. 

In classical optical absorption measurements, the absorption of a sample under different conditions as a function of the energy of the incident electromagnetic radiation is studied. This can be achieved in two ways one can either take a broadband source and use a spectrometer to disperse the electromagnetic spectrum, or use a monochromatic tunable source. There is also a...
