Appendix H: Fundamental Constants, Conversion Factors, and Key Data

Abstract

In this appendix (Tables H.1-H.4) we have assembled for the convenience of the reader a selection of the most recent compilation (2003) of fundamental constants relevant to the EPR field, as well as conversion equations of general interest and tables of properties of selected nuclides. As stated, we use the SI (rationalized mksC) system. TABLE H.1 Fundamental Constants a,b 1. Speed of light in the electromagnetic vacuum c ¼ 2:99792458  10 8 m s À1 (defined) 2. Magnetic constant (permeability of the vacuum) m 0 ¼ 4p  10 À7 ¼ 12:566370614  10 À7 J C À2 s 2 m À1 (defined) (also ¼ T 2 J À1 m 3 , where 1 joule (J) ¼ 1 kg m 2 s À2 C 0 and 1 tesla (T) ¼ 1 kg m 0 s À1 C À1) 3. Electric constant (permittivity of the vacuum) 1 0 ¼ m 0 À1 c À2 ¼ 8:854187817  10 À12 J À1 C 2 m À1 (defined) 4. Planck constant h ¼ 6:6260693(11)  10 À34 J s ; h=2p ¼ 1:05457168(18)  10 À34 J s 5.
