Can I define a projection if I know the spatial extent of a raster?

I have a bunch of global rasters that have no spatial information. However, I know the extent of the rasters (-180 º to 180 º longitude and -86.7167 º to 86.7167 º latitude.) Is there anyway I can assign accurate spatial information based on this information?

Thanks, -Scott
