Reactions of Ground State and Electronically Excited Atoms of Main Group Elements: a Matrix Perspective

“…Some vibrational properties of these different product types are listed in Table 2. 56,156,165,166,[184][185][186][187][188][189][190][191][192][193][194][195][196][197][198][199][200][201][202][203] The behavior of the group 2 metal atoms Be, Mg, and Ca (M) under matrix conditions is typical. 166,184,185 The ground-state ( 1 S) atoms add spontaneously to O 2 to yield the cyclic peroxo molecules (η 2 -O 2 )M: in the excited 3 P state, by contrast, they insert into the O-O bond to generate the triplet dioxo products OMO, namely, linear OBeO and OMgO ( 3 Σ g -) and angular OCaO ( 3 B 2 ).…”

“…before rupture of the O−O bond is finally brought about, to give a dioxo derivative OMO (eq 21). Some vibrational properties of these different product types are listed in Table . ,,,,− The behavior of the group 2 metal atoms Be, Mg, and Ca (M) under matrix conditions is typical. ,, The ground-state ( 1 S) atoms add spontaneously to O 2 to yield the cyclic peroxo molecules (η 2 -O 2 )M: in the excited 3 P state, by contrast, they insert into the O−O bond to generate the triplet dioxo products OMO, namely, linear OBeO and OMgO ( 3 Σ g - ) and angular OCaO ( 3 B 2 ). Intriguingly, the outcome may be influenced by the choice of the matrix host, according to its ability to quench the excited metal atoms .…”
