Any dataset here, as the library's Tabulated material (bromotrichloromethane/chang-2024).

# ... load cbrcl3 as above, then:
sim = ls.Simulation(
    particles=[ls.Particle(shape=ls.Sphere(radius_nm=50), material=cbrcl3)],
    medium_index=1.0,
    wavelengths=ls.WavelengthRange(start_nm=400, stop_nm=1000, num=81),
)
res = ls.solve(sim)  # exact Mie for a sphere
print(res.q_ext)     # extinction efficiency at each wavelength

Same spec runs with DDA, FDTD, BEM or T-matrix: ls.compare(sim, ["mie", "dda"]).

About CBrCl3 (Bromotrichloromethane)

Methane (CH₄) is the simplest alkane and is a colorless, odorless gas under standard conditions. It is the primary constituent of natural gas and is notable for being a potent greenhouse gas. In the environment, methane is produced during the anaerobic decomposition of organic matter, such as in wetlands, ruminant digestion, and landfills. It can also be found in various industrial processes and is used as a fuel for heating and electricity generation. In the realm of optics, methane's refractive properties might be of interest, especially when considering its potential presence in gaseous atmospheres of extraterrestrial bodies.

Other names: CBrCl3, Methane, CH₄, Tetrahydridocarbon
