1. partly based on observation or experiment and partly on theory
Usage: scientific; technical

Examples

• The semiempirical method combines theoretical calculations with experimental data.
• Researchers used a semiempirical approach to predict the compound’s properties.
• The semiempirical model provided more accurate results than pure theory alone.
• Many chemistry software programs rely on semiempirical methods for molecular modeling.
• The semiempirical formula was derived from both quantum mechanics and laboratory measurements.
• Scientists often prefer semiempirical techniques when full theoretical calculations are too complex.
