double | dust_draine_beta2 (double Nm, double Nc) |
double | dust_PAHDebModeE (unsigned j, double TDebye, double Nm, double beta, double n) |
double | dust_DebModeE (unsigned j, double TDebye, double Nm, double beta, double n) |
double | dust_nCCOPmodes (double a) |
double | dust_nCCIPmodes (double a) |
double | dust_nCHmodes (double a) |
double dust_DebModeE | ( | unsigned | j, | |
double | TDebye, | |||
double | Nm, | |||
double | beta, | |||
double | n | |||
) |
Like dust_PAHDebModeE but no shift to 2 and 3 energy levels
double dust_draine_beta2 | ( | double | Nm, | |
double | Nc | |||
) |
This is the shifting factor for the Debey model of eigenspectra. Seen eq 7 of the Draine & Li paper.
Nm | number of modes with this nominal Debey temperature. | |
Nc | number of carbon atoms. |

double dust_nCHmodes | ( | double | a | ) |
Returns the number of C-H modes (all three have same degeneracy)

double dust_PAHDebModeE | ( | unsigned | j, | |
double | TDebye, | |||
double | Nm, | |||
double | beta, | |||
double | n | |||
) |
This return the energy of the jth mode using the Debye approximation, given the Debye temperature TDebye, the number of modes Nm and the shifting factor beta, and n is the dimensionality of modes.
This is only valid for PAHs as it shifts the energies of the second and third state.
