-Minor but observable peak shifts of negligible-polar phonons were expected between different incidence configurations,
-  due to non-zero wavevector lengths.
+Some effects absent in the ideal model were observed experimentally,
+  including minor but observable peak shifts of negligible-polar phonons between different incidence configurations,
+  and the observability of the E#sub[1]-1 mode in normal incidence Raman experiments.
+The peak shifts were considered caused by the non-zero wavevector lengths of phonons.
 In our calculations, compared to normal incidence,
-  the spacing between the E#sub[2]-1 mode and E#sub[2]-2 mode decreased by 0.49 cm#super[-1] under edge incidence,
-  while the A#sub[1]-1 mode redshifted by 0.19 cm#super[-1].
-In our experiments, the spacing between the E#sub[2]-1 mode and E#sub[2]-2 mode decreased by 0.36 cm#super[-1],
-  while the A#sub[1]-1 mode redshifted by xxxx cm#super[-1].
+  the E#sub[2]-3 mode's frequency remained nearly unchanged,
+  while the E#sub[2]-1, E#sub[2]-2, A#sub[1]-1 modes exhibited minor but observable shifts.
+The experimental results were in good agreement with our calculations, as shown in figure and table.
+The visibility of the E#sub[1]-1 mode in normal incidence Raman experiments were attributed to the fact that
+  the incident light was not perfectly aligned along the z-axis,
+  due to the substrate's slight tilt and the converging angle of the confocal setup.
+This was confirmed by the results under different polarization configurations and different tilt angles,

-E1为什么可以被看到。
-
-E1在正入射中可以看到，尽管理论上不应该。
-这被认为是因为入射光并非完全沿z轴入射，由于衬底斜切和共聚焦汇聚角。
-通过向不同方向倾斜衬底，我们可以使这个峰变高或变低，如附图所示。
-此外，考虑到斜切方向（x方向），E1模式应该更容易在zxxz和zyxz中看到，而在zyyz中更难看到，这与实验一致。

-The E#sub[1]-1 mode was observed in normal incidence Raman experiments, despite being theoretically forbidden.
-This was attributed to the fact that the incident light was not perfectly aligned along the z-axis,
-  due to the substrate's slight tilt and the converging angle of the confocal setup.
-This was confirmed by tilting the substrate in different directions,
-  which caused the peak to become more or less pronounced, as shown in the inset figure.
-Furthermore, considering the tilt direction (x-direction),
-  the E#sub[1]-1 mode should be more easily observed in the zxxz and zyxz configurations,
-  while being more difficult to detect in the zyyz configuration,
-  which is consistent with our experimental observations.
