Bohr's hydrogen spectrum

http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch6/bohr.html WebSommerfeld (in 1916) expanded on Bohr’s ideas by introducing elliptical orbits into Bohr’s model. Sommerfeld’s improvement allowed the Bohr model to explain the splitting of the Balmer lines when the hydrogen atom was in an electric field. Electric field splitting of lines is known as the Stark effect.

WebIn physics and chemistry, the Lyman series is a hydrogen spectral series of transitions and resulting ultraviolet emission lines of the hydrogen atom as an electron goes from n ≥ 2 to n = 1 (where n is the principal quantum number), the lowest energy level of the electron.The transitions are named sequentially by Greek letters: from n = 2 to n = 1 is called Lyman … WebThe Bohr model was based on the following assumptions. The electron in a hydrogen atom travels around the nucleus in a circular orbit. The energy of the electron in an orbit is proportional to its distance from the nucleus. … labcorp thomas johnson drive frederick md fax https://hotel-rimskimost.com

WebFor the hydrogen atom, ni = 2 corresponds to the Balmer series. There are other series in the hydrogen atom that have been measured. The Lyman series is a set of ultraviolet lines that fit the relationship with ni = 1. A series in the infrared region of the spectrum is the Paschen series that corresponds to ni = 3.
