Russian term or phrase: т.д.т.
I have a table concerning chemical shifts 1H, δ, and 19F, δ, in ppm..
1H and 19F NMR spectra of alkanes and alkenes

The values are like:
6.2 T. T (α) 42.7 T. T. Д. (1)
4.0 T. T (β) 25.6. Д T. T (2)

5.9 T. T (α), 46.4 T. Д. T. (1),
3.6 T. T (β) 26.4. Д (2)
I am not able to get what these Т.Т., Т.Т.Д., Д.Т.Т. mean.
Could you please help me?

triplet of doublet of triplets

, tdt= triplet of doublet of triplets, dddd= doublet of doublet of doublet of doublets. IR spectra were recorded on a SHIMADZU

abbreviations: d doublet, triplet, dd= doublet of doublets, dt doublet of triplets, dq doublet of quartets, dtt doublet of triplet of triplets, br broad, u unobserved.
signal at δ -108.8 ppm as a doublet of triplet of triplets with coupling constants of 2JFP = 55.9 Hz, 3JFF = 15.0 Hz and 4JFF = 4.3 Hz.
Data for 1
H NMR spectra were
reported as follows: chemical shift (ppm, referenced to protium, s = singlet, d = doublet, t = triplet, q = quartet, quin
= quintet, dd = doublet of doublets, td = triplet of doublets, ddd = doublet of doublet of doublets, m = multiplet,
coupling constant (Hz), and integration). All other materials were obtained from Aldrich Chemical Company or
Combi-blocks and were used as received.
