Abstract
Effective temperature is the most important stellar atmospheric parameter. It is an essential prerequisite for detailed spectroscopic analyses. A discussion of the methods for determining effective temperature using stellar spectra is presented. The use of Balmer line profiles is explored and the role of spectral line depth ratios outlined. Equivalent width measurements are a powerful tool for determining effective temperature, via the excitation potential method. This is explored in detail including the sensitivity to surface gravity and metal abundance. The discussion leads to the use of spectrum synthesis fitting to determine effective temperature.
