(Laughter) We have to go a little beyond that. Now let me explain why vibrational theory has some sort of interest in it. These molecules, as you saw in the beginning, the building blocks had springs connecting them to each other.
(Smijeh) Sad ćemo malo zaći u ovo. Objasnit ću vam zašto sam se počeo zanimati za teoriju o vibracijama. One molekule, kako ste vidjeli na početku, imaju građevne materijale koji imaju opruge koje ih spajaju međusobno.
