| Band | λ(cm−1) | a | b | ω1 (cm−1) | ω2 (cm−1) | s1 | s2 | ωS1 (cm−1) | ωS2 (cm−1) |
| B777 | 108 | 0.5 | 0.58 | 100 | 100 | 0.8 | 0.5 | 0.556 | 1.936 |
| B800 | 112 | 0.130 | 0.583 | 10 | 190 | 0.183 | 0.34 | 1.149 | 3.891 |

Note that a and b are linear parameters of the C″(ω) function; ω1 and ω2 are characteristic frequencies of the first and second exponent of the C″(ω) function (see Eq. 11); s1 and s2 are linear parameters of the J(ω) function; ωS1 and ωS2 are characteristic frequencies of the first and second exponent of the J(ω) function (see Eq. 16); and λ, defined according to Eq. 12, is the reorganization energy (half of the Stokes shift) of the Bchl molecule. The parameters presented for B777 are taken from Renger and Marcus (38). Note that these parameters have been determined for the 60% glycerol solution and are kept the same for other solvents.
