M|ɛm|
the thirteenth letter of the modern and twelfth of the ancient Roman alphabet, represents historically the Greek mū and the Semitic mēm. The Phœnician form of the letter is 𐤌, whence the early Gr. and L. {egmu1}, {egmu2}, M. Its phonetic value has varied little; in Eng. it has always expressed what was doubtless its original sound, that of the bilabial nasal consonant, which is normally voiced, though when it is followed by an unvoiced consonant it has an unvoiced ending. Like the other nasals, m is capable of being used as a sonant or vowel, denoted by |(ə)m| in the phonetic notation here employed; but in Eng. this occurs only after |ð| and |z| at the end of words (of Gr. etymology), as rhythm, spasm, schism, and the suffix -ism; in these words many speakers substitute |-əm|. The letter is never silent, exc. initially before n in Gr. derivatives, as mnemonic.

5. Further symbolic uses in science.
a. In Physics M is used to designate the series of X-ray emission lines of longer wavelength than the L-series obtained by exciting the atoms of any particular element (cf. L 7 a); these arise from electron transitions to the atomic orbit of third-lowest energy, with principal quantum number 3, which is thus termed the M-shell, and electrons in this shell M-electrons. M-capture, the capture by an atomic nucleus of one of the M-electrons.
1911C. G. Barkla in Phil. Mag. XXII. 408 From the similarity of the behaviour of all the elements we must then admit..the possibility of further series M, N, &c. 1923H. L. Brose tr. Sommerfeld's Atomic Struct. & Spectral Lines iii. 145 Electronic transitions that end in the M-shell, furnish differences of energy that correspond to emissions of lines of the M-series. 1924Phil. Mag. XLVIII. 722 Krypton..has 2 K, 8 L, 18 M, and 8 N electrons. 1924R. W. G. Wyckoff Struct. Crystals ii. 72 The M-lines have been observed from the elements from dysprosium..to uranium. 1934H. E. White Introd. Atomic Spectra xvi. 306 Like the K and L series lines, the M series lines follow nearly straight lines on a Moseley diagram. 1968Physical Rev. CLXVI. 944/2 The predicted exchange–overlap correction..is even larger for M capture than for L capture. 1970E. P. Bertin Princ. & Pract. X-Ray Spectrometric Analysis i. 27 An electron that has enough energy to expel a K electron obviously can also expel any L or M electron.
b. In Physics m and M denote magnetic quantum numbers, corresponding to the component of an angular momentum (often indicated by a subscript) in some physically distinguished direction (usu. that of a magnetic field). [Introduced by A. Landé 1921, in Zeitschr. f. Physik V. 233.]
m is usually used for a single particle, and M for an assemblage of particles.
1923Jrnl. Optical Soc. Amer. VII. 415 The numbers at the left show the magnetic quantum number m characterizing each level. 1926Proc. R. Soc. A. CXII. 80 It is necessary also..to take into consideration the effect of the orientation of orbits with respect to an imaginary magnetic field, and such orientation involves a fourth quantum number m, which in turn is itself composite and is equal to the vector sum of two subsidiary quantum numbers ma and ms. 1962H. D. Bush Atomic & Nucl. Physics ii. 38 It is necessary to characterize electrons in atoms by four quantum numbers n, l, ml, ms. 1967W. R. Hindmarsh Atomic Spectra i. vi. 72 We can also perform a simple calculation for the case where the Zeeman splitting is large compared with the hyperfine structure but still small compared with the fine structure. In this case the quantum numbers MJ and MI (which defines the z-component of the nuclear spin) are well defined, but not J and I.
