Erratum to: “The Fluorescence and Electronic Structure of Phenyl-Substituted Tetraazachlorin Molecules” [Optics and Spectroscopy 117, 722 (2014)]

should read “porphyrazine” instead of “porphyrazin”;

should read “intersystem crossing” instead of “intercombinational conversion”;

should read “mirror-symmetrical” instead of “reflection-symmetric”;

should read “fluorescence enhancement” instead of “fluorescence buildup.”

Page 722, Abstract, lines 9–10 from the top, the sentence should read:

This characteristic increases upon tetrapyrrole phenylation.

Page 727, left column, lines 17–18 from the top, the sentence should read:

The vibronic transition parts of the emission spectrum are diffuse, (…)

Page 727, left column, lines 29–30 from the top, the sentence should read:

Note that the Stokes shift in these cases is relatively large.

Page 729, left column, lines 8–10 from the bottom, the sentence should read:

For H₂Ph₈TAC^mp and H₂Ph₆TAC^tm, the enhancement of fluorescence is weaker than in the former case: on cooling, τ_F is increased by a factor of 4–5 in MTHF and by a factor of only 2.6–3 in toluene.

Page 729, right column, lines 9–10 from the footnote, the sentence should read:

It is seen from Table 1 that our results agree reasonably well with previously reported data.

Page 730, left column, lines 16–19 from the top, the sentence should read:

The lifetime for the outgassed H₂TAP solution in

toluene (τ_T⁰) was measured by A.S. Stasheuski as phosphorescence decay at λ_reg = 1070 nm using the setup described in [29].

Page 730, left column, lines 20–23 from the top, the sentence should read:

The τ_T value derived from the kinetics of the rise of singlet oxygen luminescence [26] for the nonoutgassed solution at λ_reg = 1272 nm is 162 ns;

Page 730, right column, lines 25–27 from the top, the sentence should read:

Therefore, for H₂TAP (λ_F⁰⁰≈ 620 nm), the internal conversion probability should not be high.

Page 731, left column, the heading of Table 2 should read:

Bond lengths in the porphine macrocycle (Å).

Page 731, left column, lines 3–6 from the top, the sentence should read:

For elucidating the mechanism of the deactivation of the S₁ state, it was of essential interest to see whether the enhancement of H₂TAP fluorescence would be observed at 77 K.

Page 733, left column, lines 2–3 from the top, the sentence should read:

The corresponding difference for the H₂P–H₂C pair is 0.013 Å.

Page 733, left column, lines 14–16 from the top, the sentence should read:

The macrocycle undergoes additional contraction, and the symmetry of its conjugated system is very close to D_2h.

Page 733, right column, line 21 from the top should read:

Replacement of the methine bridges (…)

Page 734, left column, lines 8–11 from the figure caption, the sentence should read:

This is the main reason of the large bathochromic shift of the Soret band of H₂Ph₈TAP and MgPh₈TAP [16] relative to H₂TAP and MgTAP, respectively.

Page 734, left column, lines 1–4 from the bottom, the sentence should read:

The complete INDO/Sm calculation yields the corresponding quantitative characteristics, which are in good agreement with experimental data (see below).

Page 740, left column, reference no. 25 should read:
