_exptl_crystal.density_meas_lt
Name:'_exptl_crystal.density_meas_lt'
Definition:
The value below which the density measured using standard chemical and physical methods lies. The units are megagrams per cubic metre (grams per cubic centimetre). _exptl_crystal.density_meas_gt and _exptl_crystal.density_meas_lt should not be used to report new experimental work, for which _exptl_crystal.density_meas should be used. These items are intended for use in reporting information in existing databases and archives which would be misleading if reported under _exptl_crystal.density_meas.Examples:
1.0 | specimen floats in water |
5.0 | upper limit for the density (only the range within which the density lies was given in the original paper) |
Type: float
Mandatory item: no
Alias:_exptl_crystal_density_meas_lt (cif_core.dic version 2.3)
The permitted range is [0.0, infinity)
