chirality
Explanation:
A palavra que o Sr. José Lopes procurava é quiralidade ("chirality", em inglês). É um termo muito usado em química (mais especificamente em assuntos de estereoquímica), mas ainda continua arredado dos dicionários portugueses (consultei vários; apenas o Novo Dicionário Aurélio (2ª ed., 1986) apresenta as entradas Quirais e Quiralidade).

Chirality -
handedness, the quality of having non-superimposable mirror images. (http://hexane.chem.uiuc.edu/cyberprof/public/chemistry/102x/...

Chirality

Physics: The characteristic of an object that cannot be superimposed upon its mirror image.

Particle physics: The quantum number of particles with semi-integer spin that are allowed to have only one spin state with respect to an axis of quantization parallel to the particle's momentum. For a free particle its chirality coinside with its helicity. If the particle's spin is always parallel to its momentum, it has positive chirality; antiparallel, negative.
