Abstract

Some additional multiplets arising from combinations between triplet terms of Pb III have been found. These are

6 {}^{3}P_{0, 1, 2} - 8 {}^{3}S_{1}

6 {}^{3}P_{0, 1, 2} - 7 {}^{3}D_{1, 2, 3}

7 {}^{3}P_{0, 1, 2} - 7 {}^{3}D_{1, 2, 3}

and

6 {}^{3}P_{0, 1, 2} - p p {}^{3}P_{1}

. Twenty-one lines arising from combinations between singlet terms and intercombinations between singlet and triplet terms have been identified. Of particular interest is the

pp {}^{1}D_{2}

term which is found in combination with

6 {}^{3}P_{1, 2}

6 {}^{1}P_{1}

6 {}^{3}F_{2, 3}

and

6 {}^{1}F_{3}

. Seven newly found lines of Tl II are also given, which correspond to some of the Pb III combinations classified in this paper.
