##4:4-atom SHAKE cluster with three bonds
Shake Atoms
#ID a b c ##flag=0 没有abc,忽略
1 1 2 3 ##flag=1 ID a(中心原子ID) b c
2 1 2 3 ##flag=2 ID a (ID of atom in bond with the lowest ID) b(ID of atom in bond with the highest ID)
3 1 2 3 ##flag=3 ID a(中心原子ID) b,c(IDs of other two atoms bonded to the central atom)
##flag=4 ID a(中心原子ID) b,c,d(IDs of other three atoms bonded to the central atom)
Shake Bond Types
#ID a b c ##flag=0 没有abc,忽略
1 1 1 1 ##flag=1 a(bondtype of the bond between the central atom and the first non-central atom) b(bondtype of the bond between the central atom and the 2nd non-central atom) c(the angle type of the angle between the 3 atoms)
2 1 1 1 ##flag=2 a(bondtype of the bond between the 2 atoms in the cluster)
3 1 1 1 ##flag=3 a(bondtype of the bond between the central atom and the first non-central atom) b(bondtype of the bond between the central atom and the 2nd non-central atom)
##flag=4 a(bondtype of the bond between the central atom and the first non-central atom) b(bondtype of the bond between the central atom and the 2nd non-central atom) c(bondtype of the bond between the central atom and the 3rd

Special Bond Counts
#ID 1-2原子紧邻 1-3 1-4
1 2 0 0 ## 对于atom1 也就是o来说
2 1 1 0
3 1 1 0
##
## atom1
## o
## / \
## atom2 h h atom3
##
## atom1 atom2就是1-2紧邻,atom1 atom3同理;--> 两个相邻原子间隔了1个键
## atom2和atom3呢?三个原子间隔了2个键
## 显然 1-2原子紧邻 2个 ,1-3,1个,1-4,0个
Special Bonds
1 2 3 ### ID 1-2紧邻 1-3
