I would think that normal molecular hydrogen could have more than one orbital spin state for its two electrons. Thus, a notation of H(0) would not be correct for some normal hydrogen. Please take a look (for example) at: Nuclear particle decay in a multi-MeV beam ejected by pulsed-laser impact on ultra-dense hydrogen H(0) Leif Holmlid International Journal of Modern Physics E, 24:11 (2015) 1550080 (18 pages) >From the paper: “Two different forms of ultra-dense hydrogen H(0) exist, namely ultra-dense protium p(0)1 and ultra-dense deuterium D(0).2,3 The names of these materials have recently been changed from p(−1) and D(−1) to indicate that the orbital angular momentum of the electrons is zero.3”
